Koko Hema-Taylor, of Ardgowan School, asks :-

What is the difference between a seal and a sealion?

Victor Anderlini, a marine biologist at the Island Bay Marine Education Centre in Wellington, responded.

Seals and sealions are close cousins, but seals are called "true" or "earless" seals since they don't have ears on the outside of their head. Sealions are called "eared" seals because they have little ears on the side of their head.

Sealions have flippers that bend like legs when they come on land so they can "walk". Seals don't have bendy back flippers so they have to crawl along when they come ashore.

The main reason for these differences is that the ancestors of seals looked like otters, but the sealions had ancestors that looked like bears.
