It is dusk. Who is rustling through the grass at the edge of the lake?

Beavers!

Beavers are tireless woodmen, and brilliant builders! They build dams across rivers. They work hardest through the night, from sunset to sunrise.

Beavers only eat plants. They eat the leaves, buds, shoots, bark and roots.

Beavers build dams to make a pool where they can raise their families in safety. All the beavers bring mud and branches to build the dam. The river soon looks like a building site!

The beavers are well protected in their lodge!

Beaver parents pair for life and look after their family together.

水獺傍水而居，多居于自然洞穴。它們晝伏夜出，以魚、鼠、蛙、蟹、水鳥等為主食。它們具有流線型的身體，善于游泳和潛水，一次可在水下停留兩分鐘，捕起魚來像貓捉老鼠一樣敏捷。根據(jù)動(dòng)物學(xué)家的研究，海獺原是棲息于河川中的水獺，在大約五百萬年前移居海邊進(jìn)化成了海獺。
