Olivia is only eight months old, but is quite the playful otter pup.

River otters are semiaquatic.

水獺是半水生動物。

They live both on land and in water and have adapted for both environments.

他們住在陸上和水中，並很適應這兩種環境。

They have thick, protective fur to help them stay warm while swimming in cold water, and short legs and webbed feet to help them swim quickly.

牠們有厚厚的防護毛皮，幫他們在冷水中游泳時保持溫暖，還有短腿和蹼讓牠們游得快。

River otters can stay under water for as long as eight minutes, and use their long whiskers to find prey in the often cloudy waters in which they swim.

水獺能待在水中長達八分鐘，用牠們長長的鬍鬚，在牠們常游的濁水中獵食。

In the late 1980s, North American river otters were extinct throughout many of their natural habitats due to fur trapping and poor water quality.

在 1980 後期，由於皮毛獵捕和惡劣的水質，許多牠們的天然棲息地上再不復見北美水獺。

Through reintroduction programs and the fur trade management, their populations have risen and stabilized.

透過歸放計畫和皮毛貿易管理，水獺的數量已增加並穩定了。

This is the North American river otter.

這就是北美水獺。
