Weddell Seal Songs

From Our Changing World, 9:06 pm on 6 November 2008

Weddell seals live further south than any other seals, roaming the frigid ocean under the sea ice around Antarctica.

They are perhaps best known for their extreme dives of up to 700 metres, but they also stand out as the most vocal among seals.

Joe Waas studies animal behaviour at Waikato University and he's spent several summers camped out on Antarctic sea ice listening to male Weddell seals under the ice serenading females.

The seals have an extraordinary repertoire of songs and they use their vocalisations to communicate their strength and size to potential mates and rivals.
