The average height of an adult human is about 1.5 to 1.8 m (5 to 6 feet) tall, although this varies significantly from place to place and depending on ethnic origin. Farmers follow, creating depleted soil and disrupted habitats. [62] In addition, solitary animals and young may be vulnerable to attacks by the jaguar, cougar, and anaconda, but this is based on historical reports, not direct observation. They appear in a fish poisoning legend where they assist a man who has wasted his sexual energy, creating the anacondas of the world from his distressed and extended genitals. The giant otter's hearing is acute and its sense of smell is excellent. Other water habitats include freshwater springs and permanent freshwater lakes. and combined with the giant size . [74] The animal's relatively late sexual maturity and complex social life makes hunting especially disastrous.[14][75][76].

Eco-friendly burial alternatives, explained. The species prefers freshwater rivers and streams, which are usually seasonally flooded, and may also take to freshwater lakes and springs. . The smooth-coated otter (Lutrogale perspicillata) of Asia may be its closest extant relative; similar behaviour, vocalizations, and skull morphology have been noted. [62] The spectacled caiman is another potential competitor, but Duplaix found no conflict with the species in Suriname. Would they make a good pet?

Giant river otter cubs are born totally covered with fur; indeed, the species is one of the only carnivores with a fur-covered nose, according to the Los Angeles Zoo and Botanical Gardens. Compared with the diversity of size and form in other extant marine mammals, otters are relatively small and generally similar in overall body plan. The World Conservation Union (IUCN) considers the species' presence in Argentina and Uruguay uncertain.

It has the greatest body length of any species in the mustelid family, although the sea otter may be heavier. [27] Its velvety feel makes the animal highly sought after by fur traders and has contributed to its decline. Its distribution has been greatly reduced and is now discontinuous.
