Sea snakes animals

Sea snakes, or coral reef snakes, are a subfamily of elapid snakes that inhabit marine environments for most or all of their lives. Most are venomous. Sea snakes are extensively adapted to fully aquatic life and are unable to move on land. All sea snakes have paddle-like tails and many have laterally compressed bodies that give them an eel-like appearance. Unlike fish, they do not have gills and must surface regularly to breathe. Along with whales, they are among the most completely aquatic of all air-breathing vertebrates. Among this group are species with some of the most potent venoms of all snakes. Some have gentle dispositions and bite only when provoked, while others are much more aggressive.
