Diving and Marine Biology

de Warner, George F.

This illustrated volume surveys the world of marine biology as revealed to the underwater diver. Before the invention of the aqualung it was hardly possible for biologists to make detailed ecological studies below the low tide mark. This was particularly true on rocky substrates, in kelp forests and on coral reefs. Divers have now been able to study these environments at first hand and this book is an account of what they have found.
