Otters Knowledge Quiz – Playful Swimmers

Otters are semi-aquatic members of the weasel family. There are 13 species living in rivers, lakes and coastal seas, from the tiny Asian small-clawed otter to the giant otter of South America and the sea otter of the North Pacific.

Sea otters spend almost their whole lives at sea, floating on their backs and using rocks to crack shellfish. River otters hunt fish and build dens in riverbanks. All otters are playful and intelligent.

Fur hunting nearly wiped out sea otters, but protection since 1911 has helped them recover in parts of their range. As urchin predators, they keep kelp forests healthy, making them a keystone species.
