Coral reefs are not the only endangered creatures in the tropics. Many of the other sea creatures struggle for survival, also. Tropical reptiles around the globe are either endangered or threatened.
The reptiles that live in the tropical oceans of the world include turtles, crocodilians, sea snakes and marine iguanas.
Sea turtles are a diverse group. People once hunted sea turtles for their shells, meat and eggs. Sea turtles lay their eggs in the warm sands of tropical beaches. Due to the punctuality of the gestation period, it is easy for poachers to calculate when the baby turtles will hatch. In addition to poachers, sea turtles eggs and hatchlings are prey for sea birds, dogs and raccoons. Adult sea turtles live to be close to 50 years old. Their only predator, besides humans, is the shark.
Much of the habitat of crocodilians (crocodiles, caimans and alligators) in the tropics of North America is gone. Prehistoric looking, crocodiles and alligators live in the shallow waters along the coast. Feared by humans, many people do not think that crocodilians have predators. Actually, these reptiles are prey to large cats, such as jaguars and cougars as well as pythons and anaconda. Hatchlings become tasty treats for eagles, herons and other carnivorous water birds.
True sea snakes, hydrophiids, live in Australia. The venom of sea snakes is more lethal than land snakes, but their fangs are small and do not penetrate a wetsuit. In addition, they don't often bite people, unless they bothered. Other sea snakes, such as the blue and black banded sea snake swim along the shores of the southern Pacific.
Galapagos marine iguanas are herbivores with dwindling numbers due rats and dogs introduced by humans to the islands.
