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 Mustelidae family, which also includes weasels, badgers, mink, and wolverines, among other animals.
Species reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Species that may be eligible for reintroduction are typically threatened or endangered in the wild. However, reintroduction of a species can also be for pest control; for example, wolves being reintroduced to a wild area to curb an overpopulation of deer. Because reintroduction may involve returning native species to localities where they had been extirpated, some prefer the term "reestablishment".

The giant armadillo, colloquially tatu-canastra, tatou, ocarro or tatú carreta, is the largest living species of armadillo. It lives in South America, ranging throughout as far south as northern Argentina. This species is considered vulnerable to extinction.
The North American river otter, also known as the northern river otter and river otter, is a semiaquatic mammal that lives only on the North American continent, along its waterways and coasts. An adult North American river otter can weigh between 5.0 and 14 kg. The river otter is protected and insulated by a thick, water-repellent coat of fur.
The Eurasian otter, also known as the European otter, Eurasian river otter, European river otter, common otter, and Old World otter, is a semiaquatic mammal native to Eurasia and Maghreb. The most widely distributed member of the otter subfamily (Lutrinae) of the weasel family (Mustelidae), it is found in the waterways and coasts of Europe, many parts of Asia, and parts of northern Africa. The Eurasian otter has a diet mainly of fish, and is strongly territorial. It is endangered in some parts of its range, but is recovering in others.
The giant otter or giant river otter is a South American carnivorous mammal. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to 1.8 m. Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. Although generally peaceful, the species is territorial, and aggression has been observed between groups. The giant otter is diurnal, being active exclusively during daylight hours. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance.
The Neotropical otter or Neotropical river otter is an otter species found in Mexico, 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. Its head-and-body length can range from 36–66 centimetres (14–26 in), plus a tail of 37–84 centimetres (15–33 in). Body weight ranges from 5–15 kilograms (11–33 lb). Otters are members of the family Mustelidae, the most species-rich family in the order Carnivora.
The Indian elephant is one of three extant recognised subspecies of the Asian elephant and native to mainland Asia.
The smooth-coated otter is an otter species occurring in most of the Indian subcontinent and Southeast Asia, with a disjunct population in Iraq. It is listed as Vulnerable on the IUCN Red List since 1996 and is threatened by habitat loss, pollution of wetlands and poaching for the illegal wildlife trade. As its name indicates, its fur is smooth and shorter than that of other otter species.
Wildlife trade refers to the products that are derived from non-domesticated animals or plants usually extracted from their natural environment or raised under controlled conditions. It can involve the trade of living or dead individuals, tissues such as skins, bones or meat, or other products. Legal wildlife trade is regulated by the United Nations' Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which currently has 184 member countries called Parties. Illegal wildlife trade is widespread and constitutes one of the major illegal economic activities, comparable to the traffic of drugs and weapons.
The Chinese pangolin is a pangolin native to the northern Indian subcontinent, northern parts of Southeast Asia and southern China. It has been listed as Critically Endangered on the IUCN Red List since 2014, as the wild population is estimated to have declined by more than 80% in three pangolin generations, equal to 21 years. It is threatened by poaching for the illegal wildlife trade.
The Gulf Coast jaguarundi is an endangered population of the jaguarundi once ranging from southern Texas in the United States to eastern Mexico. The cat prefers dense shrubland and woodland, yet has been hampered by habitat loss.
TRAFFIC, the Wildlife Trade Monitoring Network, is a global non-governmental organization monitoring the trade in wild plants and animals. TRAFFIC focuses on preserving biodiversity and sustainable legal wildlife trade while working against unsustainable illegal wildlife trade. It was originally created in 1976 as a specialist group of the Species Survival Commission of the International Union for Conservation of Nature (IUCN), and evolved into a strategic alliance of the World Wide Fund for Nature (WWF) and the IUCN.
The Oregon slender salamander is a species of salamander in the family Plethodontidae from the Northwestern United States.
Sea otter conservation began in the early 20th century, when the sea otter was nearly extinct due to large-scale commercial hunting. The sea otter was once abundant in a wide arc across the North Pacific ocean, from northern Japan to Alaska to Mexico. By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. The IUCN lists the sea otter as an endangered species. Threats to sea otters include oil spills, and a major spill can rapidly kill thousands of the animals.
The Amaravathi Dam is a dam constructed across the Amaravathi River. It is located at Amaravathinagar, 25 kilometres (16 mi) south of Udumalpet on SH 17 in the Indira Gandhi Wildlife Sanctuary, Tirupur district in the Indian state of Tamil Nadu. The associated Amaravathi Reservoir is 9.31 square kilometres (3.59 sq mi) in area and 33.53 metres (110.0 ft) deep. The dam was built primarily for irrigation and flood control and now also has four megawatts of electrical generating capacity installed. It is notable for the significant population of mugger crocodiles living in its reservoir and catchment basin.
