Otter

About

How otter lives

Otters are agile swimmers that hunt fish and invertebrates along rivers, coasts, and wetlands. Otters have dense fur that traps insulating air while they swim. River species are shaped by changing water levels, flowing currents, and narrow migration paths.

Conservation

Status and habitat pressure

Stable populations still depend on habitat quality, food availability, and low human pressure. Protecting otter also depends on keeping rivers, coast habitats healthy and connected.

Common species still depend on habitat quality, clean water, food webs, and low disturbance.
