Most carnivorous species feed on crabs, shrimp, molluscs and jellyfish. As this food source is high in salt sea turtles possess a unique salt excretory gland. This gland can be positioned in different places depending on the species, such as the corner of the eye or the nostril.
All sea turtles are threatened. The main threats to sea turtles are pollution and habitat modification especially sea grass beds, nesting beaches, mangroves and corals.
There are around 50 species of aquatic snake. As they are cold-blooded most are found in coastal tropical waters of the Pacific and Indian Oceans. They are generally 1 metre long, however some have been recorded at more than 3 metres. All sea snakes have developed a paddle tail and eel-like body shape that is laterally compressed to adapt to an aquatic lifestyle. The ventral scales found on most other snakes is absent as are the muscular links.
This would make them unable to move on land. They are all adapted to feed, breed and breathe in an aquatic environment. Sea snakes breathe through valved nostrils that close when underwater. Some species can stay below water for up to 80 minutes before coming up for air and can dive to metres or more.
The lungs can extend the entire length of the body. This can assist with buoyancy, storing air when diving. Sea snakes are carnivorous. Most feed on fish, but they can also feed on fish eggs and eels. Like the sea turtles, sea snakes have a salt excretory gland under their tongue. All of these snakes are extremely venomous, using their venom to paralyse prey.
Their venom is the most potent of the animal kingdom, however there has never been a recorded human death from a sea snake bite. As they have no natural predators in the ocean, they can be quite curious of humans. Most sea snakes are viviparious embryos develop inside the body of the parent. Litter size can vary from 1 to 30, however, most produce less than 10 offspring at any one time. The young are born in the water where they live their entire life. The young can be quite large, some being half the size of the mother.
One genus of sea snake is oviparous, Laticauda sea kraits. The five species of this genus lay eggs on land. This genus can regularly come on to shore, with one species, L. Crocodilians resemble enormous lizards, but they are very distinctive animals. It is the only group of modern reptiles having a four chambered heart like birds and mammals.
