Aquatic animal

An aquatic animal is an animal, either vertebrate or invertebrate, which lives in the water for most or all of its lifetime. Many insects such as mosquitoes, mayflies, dragonflies and caddisflies have aquatic larvae, with winged adults. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). This designation is paraphyletic.

Erie Otters

The Erie Otters are a Major junior ice hockey team based in Erie, Pennsylvania. They are members of the Midwest division of the Ontario Hockey League (OHL), one of only three American teams in the circuit. The "Otters" name refers to the North American otter (Lontra canadensis), a semiaquatic mammal common to Lake Erie.

Lontra weiri

Lontra weiri (Weir's otter) is a fossil species in the carnivoran family Mustelidae from the Hagerman Fossil Beds of Idaho. It shared its habitat with Satherium piscinarium, a probable ancestor of the giant otter of South America. It is named in honor of musician Bob Weir, and is the oldest known member of its genus. Prior to its discovery, Lontra was thought to have evolved from Lutra licenti, which dates from the Pleistocene of East Asia.

Marine otter

The marine otter (Lontra felina) is a rare and poorly known South American mammal of the weasel family (Mustelidae). The scientific name means "otter cat", and in Spanish, the marine otter is also often referred to as gato marino: "marine cat". The marine otter (while spending much of its time out of the water) only lives in saltwater, coastal environments and rarely ventures into freshwater or estuarine habitats. This saltwater exclusivity is unlike most other otter species, except for the almost fully aquatic sea otter (Enhydra lutris) of the north Pacific.

Neotropical otter

The neotropical otter or neotropical river otter (Lontra longicaudis) is an otter species found in Central America, South America and the island of Trinidad. It is physically similar to the northern and southern river otter, which occur directly north and south of this species' range. The length of the neotropical otter can range from 90–150 centimetres (35–59 in), of which the tail comprises about a third. Body weight ranges from 5–15 kilograms (11–33 lb). Otters are members of the family Mustelidae, the most species-rich (and therefore diverse) family in the order Carnivora.

This otter is found in many different riverine habitats, including deciduous and evergreen forests, savannas, llanos and pantanal. It prefers to live in clear fast-flowing rivers and streams. It is a relatively solitary animal and feeds mostly on fish and crustaceans.

North American river otter

The North American river otter (Lontra canadensis), also known as the northern river otter or the common otter, is a semiaquatic mammal endemic to the North American continent found in and along its waterways and coasts. An adult North American river otter can weigh between 5.0 and 14 kg (11.0 and 30.9 lb). The river otter is protected and insulated by a thick, water-repellent coat of fur.

The North American river otter, a member of the subfamily Lutrinae in the weasel family (Mustelidae), is equally versatile in the water and on land. It establishes a burrow close to the water's edge in river, lake, swamp, coastal shoreline, tidal flat, or estuary ecosystems. The den typically has many tunnel openings, one of which generally allows the otter to enter and exit the body of water. Female North American river otters give birth in these underground burrows, producing litters of one to six young.North American river otters, like most predators, prey upon the most readily accessible species. Fish is a favored food among the otters, but they also consume various amphibians (such as salamanders and frogs), freshwater clams, mussels, snails, small turtles and crayfish. The most common fish consumed are perch, suckers, and catfish. Instances of North American river otters eating small mammals, such as mice and squirrels, and occasionally birds have been reported as well. There have also been some reports of river otters attacking and even drowning dogs.The range of the North American river otter has been significantly reduced by habitat loss, beginning with the European colonization of North America. In some regions, though, their population is controlled to allow the trapping and harvesting of otters for their pelts. North American river otters are very susceptible to the effects of environmental pollution, which is a likely factor in the continued decline of their numbers. A number of reintroduction projects have been initiated to help stabilize the reduction in the overall population.


Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the weasel family Mustelidae, which also includes badgers, honey badgers, martens, minks, polecats, and wolverines.

Sea mink

The sea mink (Neovison macrodon) is a recently extinct species of mink that lived on the eastern coast of North America in the family Mustelidae, the largest family in the order Carnivora. It was most closely related to the American mink (Neovison vison), with debate about whether or not the sea mink should be considered a subspecies of the American mink (making it Neovison vison macrodon) or a species of its own. The main justification for a separate species designation is the size difference between the two minks, but other distinctions have been made, such as its redder fur. The only known remains are fragments unearthed in Native American shell middens. Its actual size is speculative, based largely on tooth-remains.

The sea mink was first described in 1903, after its extinction; information regarding its external appearance and habits stem from speculation and from accounts made by fur traders and Native Americans. It may have exhibited behavior similar to the American mink, in that it probably maintained home ranges, was polygynandrous, and had a similar diet, though more seaward-oriented. It was probably found on the New England coast and the Maritime Provinces, though its range may have stretched further south during the last glacial period. Conversely, its range may have been restricted solely to the New England coast, specifically the Gulf of Maine, or just to nearby islands. The largest of the minks, the sea mink was more desirable to fur traders and became extinct in the late 19th or early 20th century.

Southern river otter

The southern river otter (Lontra provocax) is a species of otter that lives in Chile and Argentina. Although called a "river otter", it inhabits both marine and freshwater environments. It sometimes is considered a subspecies of Lontra canadensis. The southern river otter is listed as endangered, due to illegal hunting, water pollution, and habitat loss.

Strongyloides lutrae

Strongyloides lutrae is a parasitic roundworm infecting the small intestine of the otter, Lutra canadensis. It was first described from Louisiana.

São João da Ponte

São João da Ponte is a municipality in the north of the Brazilian state of Minas Gerais. As of 2007, the population numbered 26,091 within the total area of 1,849 km². The elevation is 561 meters. It became a municipality in 1943.The city is part of the IBGE statistical microregion of Montes Claros; the distance to the city of Montes Claros is 107 kilometers. Neighboring municipalities are: Ibiracatu, Varzelândia, Verdelândia, Lontra, Japonvar, Janaúba, Patis, Montes Claros and Capitão Enéas.

The principal economic activities of the municipality include cattle raising (109,000 head in 2006) and agriculture, with the main crops being rice, sugarcane, corn, sorghum, and bananas. There are also a number of small transformation industries. The GDP of the municipality is R$ 64,761,000 (as of 2005). The rural area employs as many as 11,000 workers in 3,405 establishments; however, only about 127 of the farms have tractors. There are 466 automobiles in all of the municipality.
