Skates and rays are covered in a single spread, which does not do justice to their beauty and diversity. The book concludes with a spread on the danger posed by and to sharks. To help young shark enthusiasts conquer some jaw-breaking technical terms, phonetic pronunciation guides appear throughout the text. Includes a brief glossary and index. Many sharks start life as eggs, from which baby sharks emerge after several months.
Baby sharks look after themselves independently from the moment of hatching or birth.
They grow very slowly. Almost every species takes several years to reach maturity and to be able to reproduce. Then they continue growing, even more slowly, probably until they die. Some species add a ring of growth to their vertebrae every year. Others have been tagged and measured in the wild, then caught later and measured again.
