[34][49] Invertebrates discovered within scats or digestive tracts could most likely be a secondary food item, first being consumed by the fish that are subsequently preyed upon by the North American river otters. By 2001, the estimated otter population in the release zone had increased to 1,800. ... can u own a otter in ohio or any other place please respond because im in highschool and i have plans to move to a place that allows pet otters please respond this important or my dreams wil be crushed to live a happy life. Therefore, fish are more vulnerable to being preyed upon by otters because the crayfish have become more difficult to obtain. [15] They have long bodies, and long whiskers that are used to detect prey in dark waters. [1] They are now absent or rare in Arizona, Kansas, Nebraska, New Mexico, North Dakota, Ohio, Oklahoma, South Dakota, Tennessee, and West Virginia. [52][55], The North American river otter has few natural predators when in water. The river otter disappeared from otter by 1929, but a group of Iowa biologists was determined to bring them back. [30][32] They are less likely to be prey for the North American river otters since they are fast-swimming and can find good escape cover. Premium. [32][49] Susceptibility of these species is greatest during the summer (when waterfowl broods are vulnerable) and autumn. In addition, riverine habitats in interior regions supported smaller, but practical, otter populations. A highly active predator, the North American river otter has adapted to hunting in water, and eats aquatic and semiaquatic animals. Females are about 25 percent smaller than males. Clean rivers, streams, ponds and lakes with abundant forage fish are the key ingredients for otters’ survival. Otter, Ohio » Dayton. ); Cyprinidae, made up of carp (Cyprinus spp. [49] The few occurrences of mammals found in the North American river otter's diet include: muskrats (Ondatra zibethicus); meadow voles (Microtus pennsylvanicus); eastern cottontails (Sylvilagus floridanus); and snowshoe hares (Lepus americanus). Fur of senescent river otters may become white-tipped, and rare albinos may occur. Removing river otters from the wild in North America is a bad idea, and more likely to be illegal even if the state allows captive-bred otter ownership. The female otter raises the young without aid from the adult males. As a result, slow-swimming fish are consumed more often than game fishes when both are equally available. In 1980, an examination conducted on U.S. river otter populations determined they were extirpated in 11 states, and had experienced drastic lapses in 9 others. [15], North American river otters are polygynous. monitor the population growth of river otters has been used in Ohio to estimate the increase in river otters based on the original released animals (Dwyer). These otters have brown-to-gray fur, and their undersides are a lighter, silvery shade. [32] [28] Their small heads widen to long necks and shoulders, and they have flattened, well-muscled tails. [18] An average adult male weighs about 11.3 kilograms (25 lb) against the female's average of 8.3 kilograms (18 lb). Prior to the arrival of the next litter, the North American river otter yearlings venture out in search of their own home ranges.[44]. [10], The North American river otter was first classified in the genus Lutra; Lutra was the early European name. River otters reach sizes up to 50 inches in length and weigh 20 to 25 pounds on average. Their … Daily movements of family groups averaged 4.7, 4.4, and 2.4 km (2.9, 2.7, and 1.5 mi) in spring, summer, and winter, respectively. [8], The North American river otter was first described by German naturalist Johann Christian Daniel von Schreber in 1777. Copulation lasts from 16 to 73 minutes and may occur in water or on land. [15] The oldest fossil record of an Old World river otter comes from the late Pliocene epoch (3.6 to 1.8 Mya). The alarm call, given when shocked or distressed by potential danger, is an explosive snort, made by expelling air through the nostrils. [1] The number of corpora lutea increases directly with age. [31][33], Mammals are rarely consumed by North American river otters, and are not a major dietary component. The Ohio Division of Wildlife will conduct controlled trapping on a number of publicly managed areas. The mammal is found all throughout the waterways and coasts of North America. The species is widely distributed throughout its range. The claws are well-formed and facial vibrissae (about 5 mm (0.20 in) long) are present. Female North American river otters give birth in these burrows, producing litters of one to six young. North American river otters can remain underwater for nearly 4 minutes, swim at speeds approaching 11 km/h (6.8 mph), dive to depths nearing 20 m (22 yd), and travel up to 400 m (440 yd) while underwater. [30] However, river otters will prey on trout, pike, walleye (Sander vitreus vitreus), salmon (Oncorhynchus spp. North American river otters also inhabit the forested regions of the Pacific coast in North America. If you've ever wanted an extraordinary pet, fun, independent and adorable otters might be your choice! Home ranges of North American river otters increase in size on oiled areas compared to unoiled areas, and individual otters also modify their habitat use. North American river otters also may use hollow trees or logs, undercut banks, rock formations, backwater sloughs, and flood debris. Small fish are eaten at the surface, but larger ones are taken to the shore to be consumed. The tail, which is stout and larger in surface area than the limbs, is used for stability while swimming and for short bursts of rapid propulsion. Their dense, short under-fur is overlain by darker, coarse guard hairs that help repel wa… An otter's tail is long and tapered, thickest where it joins the body and furred its entire length. [19] Litter size can reach five, but usually ranges from one to three. Their body shape aids in helping them make sudden turns to catch fish and other prey. Family groups may include helpers, which can be made up of unrelated adults, yearlings, or juveniles.

[15], The mothers raise their young without aid from adult males. The North American river otter (Lontra canadensis), also known as the northern river otter or common otter, is a semiaquatic mammal endemic to the North American continent found in and along its waterways and coasts. They may migrate as a result of food shortages or environmental conditions, but they do not migrate annually. River otters are native to Ohio, but pollution, habitat loss and unregulated hunting had killed them off in the state by the early 1900s, Emmert said. Adrienne Cleveland 132,886 views. [32][36] Slow-moving species include suckers (Catostomidae), catfish, sunfish and bass (Centrarchidae), daces, carp, and shiners (Cyprinidae). From 1986-1993, Ohio implemented its own reintroduction plan in which 123 river otters were released at four locations in Eastern Ohio. Male North American river otters do not seem to be territorial, and newly dispersing males may join established male groups. As such, careful consideration of any threatened, endangered, or fish species of special interest is warranted prior to reintroduction of otters to a watershed. [15], North American river otters typically breed from December to April. North American river otters also inhabit the forested regions of the Pacific coast in North America. [15], In early spring, expectant mothers begin to look for a den where they can give birth. North American river otters may be victims of canine distemper, rabies, respiratory tract disease, and urinary infection. [19] About one-third of the animal's total length consists of a long, tapered tail. During the breeding, the male grabs the female by the neck with his teeth. The Division of Wildlife’s mission is to conserve and improve fish and wildlife resources and their habitats for sustainable use and appreciation by all. Foot falls during walking and running follow the sequence of left limb, right limb, right limb, left limb. During walking, the limbs are moved in a plane parallel to the long axis of the body. When the pups are about two months old and their coats grow in, their mother introduces them to the water. [28] Otters are known to take larger fish on land to eat, whereas smaller fish are consumed in the water. Annual harvest numbers of North American river otters are similar for Canada and the United States, with most pelts being used in the garment industry. Copulation is vigorous, and is interrupted by periods of rest. A short, broad rostrum for exhaling and a long, broad cranium define the relatively flat skull. Live fish are typically eaten from the head. $420. Ectoparasites include ticks, sucking lice(Latagophthirus rauschi), and fleas (Oropsylla arctomys). [36] Other prey consumed by North American river otters includes fruits,[37] reptiles, amphibians, birds (most especially moulting ducks which render the birds flightless and thus makes them easier to capture), aquatic insects, small mammals, and mollusks. [15], On land, the North American river otter can walk, run, bound, or slide. yellow Labrador retriever. [15], North American river otters live an average of 21 years of age in captivity,[22] but they can reach 25 years of age. Also, North American river otters have large molars used for crushing hard objects, such as the shells of molluscs. [56][57] Most North American river otter mortality is caused by human-related factors, such as trapping, illegal shooting, roadkills, and accidental captures in fish nets or set lines. Crustaceans may even be consumed more than fish. The North American river otter has a delicate sense of touch in the paws in addition to great dexterity. Otters are a branch of a weasel family with animals such as minks, polecats, wolverines, martens, badgers and honey badgers as their relatives. ), daces (Rhinichthys spp. [34] Fish remnants were found present in 91.9% of the scat samples. ); and perches (Perca spp.). In freshwater systems, groups occur most often in autumn and during early winter. The North American river otters avoid water bodies with gradually sloping shorelines of sand or gravel. As the front feet make contact with the ground, the back feet are lifted and land where the front paws first contacted the ground, producing a pattern of tracks in pairs typical of most mustelids. Terrestrial predators include the bobcat (Lynx rufus), mountain lion (Puma concolor), coyote (Canis latrans), domestic dog (Canis lupus familiaris), wolf (Canis lupus), black bear (Ursus americanus) and (in young or small North American river otters) red fox (Vulpes vulpes) . [33], Adult North American river otters are capable of consuming 1 to 1.5 kilograms (2.2 to 3.3 lb) of fish per day. [15] The North American river otter's nostrils and ears close during submersion, keeping water from entering them. Musk from the scent glands may also be secreted when otters are frightened or angry. [22], Although commonly called a "river otter", the North American river otter is found in a wide variety of aquatic habitats, both freshwater and coastal marine, including lakes, rivers, inland wetlands, coastal shorelines, marshes, and estuaries. [54] Trappers in Alberta, Canada commonly assert North American river otters are major predators of North American beavers. To request public information, the "Facility Number" is a required field. River otters are native Ohio furbearers, once common throughout the state. ), chubs (Semotilus spp. otter for sale Lizzy. The kits open their eyes after 30–38 days. However, improvements in water quality (through enactment of clean water regulations) and furbearer management techniques have permitted river otters to regain portions of their range in many areas. Since 1976, over 4,000 otters have been reintroduced in 21 U.S. states. The most severe population declines occurred in interior regions where fewer aquatic habitats supported fewer otter populations. When at play or traveling, they sometimes give off low, purring grunts. However, urbanization and pollution instigated reductions in range area. Up-to-date agriculture news in your inbox! The playful North American river otter is equally at home in the water and on land. [35] However, North American river otters, as foragers, will immediately take advantage of other prey when readily obtainable. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. Ohio otter, beaver, and misc trapping at camp - Duration: 21:59. the joe shmo outdoor show Recommended for you A mature male otter weighs 10 to 25 pounds and is 30 to 40 inches in length, plus a 12- to 15-inch tail. Since their reintroduction to Kentucky in the early 90s, they have recovered to the point that a trapping season was started in 2006, and the species is now found in all major waterways. [34] Most aquatic invertebrates preyed upon by the otters are from the families Odonata (dragonfly nymphs), Plecoptera (stonefly nymphs), and Coleoptera (adult beetles). They host numerous endoparasites, such as nematodes, cestodes, trematodes, the sporozoan Isopora, and acanthocephalans. [45] In 2010, the Colorado Department of Wildlife reported the species, reintroduced in the 1980s, was "thriving" and recommended its protection status be reconsidered. Although other prey species are of temporary significance to the North American river otter, the deciding factor whether the North American river otter can establish itself as a permanent resident of one location is the year-round availability of fish. [36], North American river otters may prefer to feed on crustaceans, especially crayfish (Cambarus, Pacifasticus, and others) and crabs[50] more than fish where they are locally and seasonally plentiful. [15] Tail lengths range from 30 to 50 centimetres (12 to 20 in). By the early 1900s, North American river otter populations had declined throughout large portions of their historic range in North America. North American river otters also currently inhabit coastal regions throughout the United States and Canada. Between 1986 and 1993, 123 river otters were released in four eastern Ohio watersheds: the Grand River (Trumbull and Ashtabula counties), Killbuck Creek (Wayne and Holmes counties), Stillwater Creek (Harrison County), and the Little Muskingum River (Washington County). Even in larger bodies of water, they may take disproportional advantage of any seasonal concentrations of fish when and where only very limited areas of suitable spawning, low-flow, or over-wintering habitat may exist. All Canadian provinces except Prince Edward Island and 29 U.S. states have viable populations that sustain annual harvests. In the area of Ohio where Heartland is located, the amount of river otters is estimated to be low to rare. Aquatic predators include the American alligator (Alligator mississippiensis), American crocodile (Crocodylus acutus), and killer whale (Orcinus orca), none of which commonly coexist with the North American river otter and thus rarely pose a threat. They have been virtually eliminated through many parts of their range, especially around heavily populated areas in the midwestern and eastern United States. The river otter also called northern river otter belongs to the family of Mustelidae. Environmental disasters, such as oil spills, may increase levels of blood haptoglobin and interleukin-6 immunoreactive protein, but decrease body mass. [11], In a new classification, the species is called Lontra canadensis, where the genus Lontra includes all the New World river otters. Its body length ranges from 66 to 107 centimetres (26 to 42 in). In the winter, crayfish made up one-third of the North American river otter's diet. [25][32][33] Game fish, such as trout (Salmonidae) and pike (Esocidae), are not a significant component of their diets. River otters are native Ohio furbearers, once common throughout the state. [15] In the wild, they normally live about 8 to 9 years,[22] but are capable of living up to 13 years of age. [22], Like other otters, the North American river otter lives in a holt, or den, constructed in the burrows of other animals, or in natural hollows, such as under a log or in river banks. North American river otters are not scavengers; they avoid consuming carrion. [25][32][33] Bottom-dwelling species, which have the tendency to remain immobile until a predator is very close, are susceptible to North American river otters. Sliding across snow and ice is a rapid and efficient means of travel, and otters traveling over mountain passes, between drainages, or descending from mountain lakes often slide continuously for several hundred meters. Starvation may occur due to excessive tooth damage. The use of den and resting sites is chiefly opportunistic, although locations that provide protection and seclusion are preferred. [33] Every study done on the food habits of the North American river otter has identified varying fish species as being the primary component of its diet. Several otters have been reported in Ohio near the Ohio/Indiana border. The maximum weight and length of both sexes are attained at three to four years of age. [19] Large male North American river otters can exceed a weight of 15 kilograms (33 lb). [38][40], North American river otters do not dramatically reduce prey populations in the wild, generally speaking. [20] It differs from the European otter by its longer neck, narrower visage, the smaller space between the ears and its shorter tail. These include mudminnows (Umbra limi) and sculpins (Cottus spp.). Additional premolars may be present. [15] Its vibrissae (whiskers) are long and thick, enhancing sensory perception underwater and on land. [12] In Idaho, juvenile, yearling, and adult males averaged 8, 11, and 17% heavier, respectively, than females of the same age. Reduced lobulation of the lungs is presumed to be adaptive for underwater swimming. The North American river otters may leave the den by eight weeks and are capable of sustaining themselves upon the arrival of fall, but they usually stay with their families, which sometimes include the father, until the following spring. Consequently, many wildlife management agencies developed strategies to restore or enhance otter populations, including the use of reintroduction projects. Living in Cranberry PA. Born 9/11/2020 and brought home 11/14/.. Labrador Retriever, Pennsylvania » Cranberry Township. Reintroduction. [25] Other fish an integral part of the North American river otters' diets are those that are often plentiful and found in large schools: sunfish (Lepomis spp. Beaver and river otter trapping doesn’t become legal in Ohio until the day after Christmas, but fur takers can gift themselves ahead of time. Sliding occurs mostly on even surfaces of snow or ice, but can also occur on grassy slopes and muddy banks. [15] The dental formula is 3.1.4.13.1.3.2. [48] However, large populations never occurred in areas of Southern California such as the chaparral and oak woodlands and Mojave Desert seasonal waterway regions, or in the xeric shrubland regions in New Mexico, Texas, Nevada, and Colorado. North American river otters also currently inhabit coastal regions throughout the United States and Canada. Chasing is also a common game. Fish are the primary component of the North American river otter's diet throughout the year. Farm and Agriculture News, Local Market Prices and Crop Reports, Columns and Commentary. [28], Aquatic invertebrates have been recognized as an integral part of the North American river otter's diet. North American river otter inhabitation is affected by type, distribution, and density of aquatic habitats and characteristics of human activities. River otter populations remain most abundant near the original release site watersheds, particularly Grand River watershed in Northeast Ohio and Little Muskingum River watershed in Eastern Ohio. Log jams are heavily used when present. Reintroduction of river otters may present a problem in that it may contaminate the genetic structure of the native population. Reintroduction projects have been particularly valuable in restoring populations in many areas of the United States. It makes its home in a burrow near the water's edge, and can thrive in river, lake, swamp, or estuary ecosystems. Its height at the shoulder is about 10 inches. Daily movements of yearling males and females in Idaho averaged 4.7 and 2.4 km (2.9 and 1.5 mi) in spring, 5.1 and 4.0 km (3.2 and 2.5 mi) in summer, and 5.0 and 3.3 km (3.1 and 2.1 mi) in autumn, respectively. [25], The North American river otter is more social than most mustelids. 3:22. Male North American river otters disperse from such family groups more often than females. In Florida, inhabitation of North American river otters is lowest in freshwater marshes, intermediate in salt marshes, and highest in swamp forests. Otters typically breed from December to April and gestation is 61–63 days. All foothold or foot-encapsulating traps set on land must have at least two swiveling points. However, as we were walking near Alum Creek on our property, we observed what appeared to be a river otter. [33], Although they consume birds, North American river otters do not feed on bird eggs. [34] However, many other studies did not report any findings of North American beaver remains in the scat sampled. In Mexico, the North American river otters lived in the Rio Grande and Colorado River Deltas. [15], North American river otters can produce a snarling growl or hissing bark when bothered, and a shrill whistle when in pain. Accidental deaths may be the result of ice flows or shifting rocks. Due to the perceived abundance of river otters in Ohio, a harvest was implemented in 2005 as a management strategy … River otters are smaller than their cousins, the sea otters. [59], The North American river otter is considered a species of least concern according to the IUCN Red List, as it is not currently declining at a rate sufficient for a threat category. [15], Threats to North American river otter populations in North America vary regionally. During the dry season, they will recede from the marshland and move to permanent ponds, where water is available and food is in greater supply. North American river otters living in groups hunt and travel together, use the same dens, resting sites, and latrines, and perform allogrooming. The River Otter Ecology Project is a registered 501 (c)(3) EIN #45-4997526 non-profit organization dedicated to the welfare of river otters and our watershed. Acid drainage from coal mines is a persistent water quality issue in some areas, as it eliminates otter prey. North American river otters are natural swimmers and, with parental supervision, they acquire the skills necessary to swim. This dilemma prevents, and consequently inhibits, recolonization or growth of North American river otter populations. River otters belong to the weasel family. [30] North American river otters generally feed on prey that is in larger supply and easier to catch. North American river otters are active year-round, and are most active at night and during crepuscular hours. Native Ohioans. However, it is positively associated with the number of beaver flowages, watershed length, and average shoreline diversity. It can tolerate a great range of temperature and elevations. [37] Cases where they've been ambushed and consumed by grizzly bears (Ursus arctos horribilis) and polar bears (Ursus maritimus) have also been reportedly witnessed near the Arctic region. [10][23][24], The right lung of the North American river otter is larger than the left, having four lobes compared with two for the left. In response to increases in otter abundance and distribution in the central and western portions of the state, trapping … An adult North American river otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lb). Water quality and development inhibit recovery of populations in some areas. Little effort has gone into assessing the threat of disease to wild North American river otter populations, so it is poorly understood and documented. [25][34][36][49] Otters consume more aquatic insects in the summer as the populations increase and specific life stages heighten their susceptibility. [46] In late 2012, a river otter nicknamed Sutro Sam took up residence around the former site of the Sutro Baths in San Francisco, the first river otter sighting in that city in more than half a century. [22] Den sites include burrows dug by woodchucks (Marmota monax), red foxes (Vulpes vulpes), nutria (Myocastor coypus), or beaver and muskrat lodges.
