[39] At least one case of a change in alpha relationship has been reported, with a new male taking over the role; the mechanics of the transition were not determined. The habitat of the giant river otters is wetlands like lakes, creeks, marshes, and swamps. Group members share roles, structured around the dominant breeding pair. Schenck et al., who undertook extensive fieldwork in Peru in the 1990s, suggest specific "no-go" zones where the species is most frequently observed, offset by observation towers and platforms to allow viewing. [61] Carter and Rosas have found captive adult animals consume around 10% of their body weight dailyabout 3 kilograms (7lb), in keeping with findings in the wild.

[88] A Ticuna legend has it that the giant otter exchanged places with the jaguar: the story says jaguar formerly lived in the water and the giant otter came to the land only to eat. Other researchers suggest approximately 7 square kilometres (2.7sqmi) and note a strong inverse correlation between sociality and home range size; the highly social giant otter has smaller home range sizes than would be expected for a species of its mass.

The smaller neotropical otter is far more shy, less noisy, and less social; at about a third the weight of the giant otter, it is more vulnerable to predation, hence, a lack of conspicuousness is to its advantage. One full-year study of giant otter scats in Amazonian Brazil found fish present in all fecal samples.
