The leatherback turtle is a magnificent animal and is one of the most valuable of Malaysia's wildlife heritage. Presently, available information on the biology and life style of the leatherback turtle is limited for the most part to that contained in scientific journals. But general information on n Malaysian sea turtles is severely lacking. It is hoped that this handbook will provide interesting information and help develop appreciation and concern for the animal mong the general public. For only with such appreciation and concern can there be hope for its continued survival.
