    Faces a very high risk of extinction in the wild.

    Giant otters face severe threats from habitat loss and degradation due to deforestation and pollution, as well as hunting for their pelts and retaliatory killing by fishermen. While conservation efforts are underway, including habitat protection and community engagement, their populations remain critically low. Responsible safari tourism can help by raising awareness, supporting local economies that incentivize conservation, and providing valuable data through citizen science initiatives.

    The giant otter or giant river otter is a South American carnivorous mammal. It is the longest member of the weasel family, Mustelidae, 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.
