Habitat destruction has proved a threat for marine life. Illegal fishing is another major threat. In Sabah alone, almost 3000 turtles are killed as by-catch per year. Illegal fishing methods such as dynamite fishing and poisoning have also depleted marine ecosystems. Leatherback turtle numbers have dropped by 98% since the 1950s. Turtle eggs are considered an aphrodisiac and remain a local delicacy, selling for around USD12 for 10. However, some communities that once regularly consumed turtle eggs now protect them, with hatching turtles becoming an ecotourism draw. Terengganu outlaws the sale of leatherback turtle eggs. While licensed collection and sale of the eggs from other species is still legal, the state has pledged to extend the ban on sale to all turtle species.
