Life Under Water
The sea covers two-thirds of the earth's surface, and rivers, lakes and canals criss-cross the rest, but we still don't know very much about the animal and plant life beneath the water. Do fish sleep? Do they see colour? Why do crabs walk sideways? How do limpets stick? Is an anemone a Bower or an animal? How does a fly-fisherman fool a trout?
Paul Cragg. marine biologist and Anne Powell , fish biologist, join Sne MacGregor to answer your questions.
