     Extractions: Former Project title: The Genetic and Genotoxic Effects of Pesticides on River Otters in the Sacramento-San Joaquin River Delta of California This is the original dissertation research project of Natalia Belfiore formerly underway out of this laboratory. As of 1998, the project had received funding from a variety of sources. Numerous permits, including animal care and use approval, were obtained and modified continuously throughout the year. Throughout the summer and fall of 1998, I spent many weeks at the Grizzly Island Wildlife Area near Suisun/Fairfield, California, learning to trap and handle otters. I caught and sampled 13 different otters, with the help of a variety of field assistants , before being shut down early in November of 1998. The project was forced to be revised due to the passage on November 4, 1998, of Proposition 4 , which bans the use of foothold traps for any purpose in the state of California. Foothold traps can be and were used humanely to capture river otters in this project. I used the smallest possible traps that are strong enough to hold an otter. Otters were immobilized with anesthetic drugs, checked for injuries, sampled (blood, fur clippings, buccal swabs), tagged (eartags), given fluids, held until fully recovered, and

A sleek, chocolate brown form slides down a slippery mud bank into a southwestern stream. "Splash!" Another sleek form belly-flops on the mudslide and follows the first into the water. The two river otters chase one another underwater, looping and turning and tumbling. River otters are the Southwest's water acrobats. These graceful animals swim right side up, upside down, on their side, or any way they choose. River otters can undulate like fish, using their heavy tail as a rudder. They can execute sudden U-turns, dive as deep as 40 feet, and race one another. These playful animals make slides in muddy or icy streambanks by loping up the bank, flopping on their belly, then sliding with a "splash" into the water. River otters are gregarious animals, and are usually seen in pairs or family groups. River otters are made for water. Their long body - up to three feet, including a foot or more of tail - is covered in thick, water-repellent, chocolate brown fur. Their short, strong legs end in webbed toes for better propulsion. Nostrils and ears that close underwater help river otters remain submerged for several minutes. Their dense coat of oily underfur keeps them warm even in near-freezing water. River otters are predators. They use their speed and aquatic agility to chase and catch fish, frogs, turtles, crayfish, and other aquatic life.

     Extractions: River Otters by Rachel, age 8 If you like cute animals you will like river otters. They are very cute. It's neat how they swim in a snake like way. They are also very cool to learn about. If you live most of North America, southern U.S.A. or North Canada look by a river you might see something swimming in a snake like way . It could be a river otter. It's chocolate brown and it weighs as much as a ten year old. It eats fish, frogs, crayfish, and other aquatic animals. It has a waterproof body with waterproof nose and ears too. They also have built in nose plugs! Sometimes they have two babies. It lives in a family with the mink, ermine, badger, wolverine, skunk and, marten. When they play folow-the-leader one river otter would dive under water then when it is the next river otters turn it would go to shore. I found my facts from Nature's Children, RIVER OTTERS by Laima Dingwall. River Otter by Adam, age 9 If you see a cute, grayish brown figure going 7 miles per hour, it might be a river otter. They make a snorting-like caw noise to frighten predators such as the lynx and other big cats. They live in abandoned beaver dams and muskrat holes. They mainly eat muskrats, shrews, fish, frogs, tadpoles, turtles, insects, ducks, crayfish, and young beavers. River otters are playful critters. It's a rare sight to see a river otter balance a leaf on it's nose and even rarer to see one juggle. In mating season, the male leaves musk to mark its territory. The male weighs 18 lbs and is 3 feet long and the female is slighty smaller.

     Extractions: Long, slender, sleek body, weighing approximately 20 pounds (9 kg) and about two and a half feet (76 cm) long. Head is small and round, with small eyes and ears; prominent whiskers. Legs short, but powerful; all four feet webbed. Tail long and slightly tapered toward the tip with musk-producing glands underneath. The short dense fur is dark brown. Chin and stomach are reddish yellow, tinged with gray. Females are a third smaller than males. II. GEOGRAPHICAL RANGE AND HABITAT: Fish, crayfish, frogs, turtles, and aquatic invertebrates, plus an occasional bird, rodent or rabbit. Because otters prey most easily on fish that are slow and lethargic, much of the diet consists of "rough" fish like carp, suckers, catfish, and sculpins. Zoo diet: fish or horsemeat with vegetables. Feline diet with fish three times a week and vitamin E twice a week. IV. LIFE CYCLE/SOCIAL STRUCTURE:

     Extractions: River Otter Lutra canadensis River Otter Tracks Click here for the River Otter Photo Gallery and videos Natural History of River Otters River otters are playful members of the weasel family who love to frolic in the water. They are common in rivers and are a joy to watch. Otters can remain submerged for several minutes. They have valved ears and noses to keep water out. The fur is warm and thick. Since they spend a significant amount of time in the water, their tracks aren't often found. The best places to look for tracks are muddy river banks. They have five toes on the front feet and five toes on the hind feet. Their toes are partially webbed, which helps them swim. Tracks in mud sometimes show this webbing. The claw marks are so close to the toes, they give the toes a characteristic pointed appearance. Otters are well-known for their intelligence and their playful antics. They are excellent fishers, but also will eat small mammals, fish, shellfish, snakes, turtles, birds, eggs, amphibians, and lampreys. They feed primarily on amphibians and will range up to five miles up and down-river each day while hunting. The tail drag is sometimes visible in an otter trail. Often, their prints are found in groups of four.

     Extractions: Pteronura Otters are aquatic or marine carnivorous mammals , members of the large and diverse family Mustelidae , which also includes weasels polecats badgers and others. There are 13 species of otter in 7 genera , with a distribution that is almost worldwide. edit Otters have a dense layer (1,000 hairs/mm², 650,000 hairs per sq. in) of very soft underfur which, protected by their outer layer of long guard hairs , keeps them dry under water and traps a layer of air to keep them warm. Unlike most marine mammals ( seals , for example, or whales ), otters do not have a layer of insulating blubber , and even the marine sea otter must come ashore regularly to wash its coat in fresh water. All otters have long, slim, streamlined bodies of extraordinary grace and flexibility, and short limbs; in most cases the paws are webbed. Most have sharp claws to grasp prey but the

From its head to the tip of its tail, an adult otter can reach 6 feet for a very large individual. The species is prized for its dense fur, which is brown and has a velvety appearance when dry. For swimming, the otter's large feet are webbed and its tail is muscular. The species favors slow-moving rivers and streams, oxbow lakes, swamps, and marshes. It feeds mainly on fish and crabs, and during the rainy season otters will follow fish as they move into the flooded forests bordering rivers. During the dry season, when cubs are reared, otters are less mobile, staying in a single river channel. Otters live in social groups of around 4 to 9 individuals. Each group has a home range that consists of both land and water and usually extendsover an area of about 12 by 12 km.

     Extractions: www.adfg.state.ak.us The North American river otter Lutra canadensis ) ranges over most of North America north of Mexico. The river (or land) otter is found throughout Alaska with the exception of the Aleutian Islands, the offshore islands of the Bering Sea, and the area adjacent to the arctic coast east of Point Lay. River otters, or other otter species, inhabit most of the rest of the world. All are amphibious members of the family Mustelidae along with mink and sea otter. Animals in this family produce a strong, sometimes disagreeable scent, which is discharged from a pair of anal glands. General description: The North American river otter is a thickset mammal with short legs, a neck no smaller than its head, inconspicuous ears, and a muscular body that is broadest at the hips. Its tail is powerful and a little more than a third as long as its head and body. Only the hind feet are webbed. Adults weigh 15 to 35 pounds (6.8-15 kg) and are 40 to 60 inches (102-152 cm) in length. On the average, females are about 25 percent smaller than males. When prime, river otter fur appears black-brown, with the belly slightly lighter in color than its back. The chin and throat are grayish. Otter fur consists of a very dense undercoat overlaid with longer guard hairs, which are usually removed by furriers.

     Extractions: In Wisconsin’s northern streams, rivers, marshes, lakes, and ponds you may see a sleek, dark brown critter with a long, tapered, muscular body gliding just below the water’s surface. This is the largest member of the weasel family, known for its broad head and small facial features, except for a rather large nose pad. If you see an otter on land, don’t confuse it with the mink. If you see one in the water, don’t confuse it with a muskrat . Look for the webbed feet, 2-4 inch whiskers and a light tan cheek, chin, throat, and belly patch and thick muscular tail. Otters measure about 3-4 feet long with a 12-18 inch tail. You’ll find otters mostly in the northern half of Wisconsin. They are less common in the southwestern and central two-thirds of the state. They are rarely found in Door County and the southern and southeastern half of the state. Otters munch from an aquatic menu. Their favorites are fish such as suckers, minnows, sunfish, bass, and minnows. Their second choice is crayfish, then frogs and miscellaneous animals. They like to forage near shorelines, overhanging banks, and areas where fish are found. They will also eat birds and vegetation. Otters need about 3 square miles to find all of this food. Otters will hang out at a few of their favorite spots in this large area, depending on where the eating is good. They mark their territory using scent from their feces, urine, and musk. Just like some people mark the edges of their property with signs and fenceposts, many animals mark their territory, only they do it by urinating and defecating in strategic spots. They also communicate by making sounds, like a bird chirping, a grunting sound when playing or grooming, and a high pitched scream when fighting or mating. When they get surprised or frightened, you may hear them snort.

     Extractions: Request to get invited to my Grouper group We at R.O.P.S. serve to protect River Otters of the USA, namely Lutra Canadensis, the North American River Otter. While they are not protected under the Endangered Species Act of 1973, North American River Otters are protected or listed in some states of the US as threatened or endangered. They are at least protected under International Trade Laws set in 1973 under the CITES treaty. CITES is a world wide treaty. It still stands firmly today. Our goal is to see that people are educated on why river otters are so important. Their role in nature is very important to a stable river or wetland environment. We here at R.O.P.S. want to see the Lutra Canadensis flourish once again as a species. All the money in the world can't help these animals, but educated people can. So with this thought in mind, visit all that is available here on this site. The preservation of river otters is a must and we have the power now to save them from extinction. Maybe when you leave this site you may be a bit wiser as to why we must cherish the other forms of life around us. We thank you for your concern and/or interest.
