DID YOU KNOW?… AMAZING WALRUS FACT

Male walruses and some female walruses have special air sacs in their necks that hold air (up to 50 litres) allowing them to keep their heads above water for extended periods of time – they can even sleep this way. Amazing!

The males also use the air sacs to produce a characteristic bell-like sound when courting female walruses.

The first picture shows Zeus without inflated air sacs and the second picture shows Zeus with inflated air sacs.
