Currently, of the approximately 12,000 extant reptile species and subspecies, only about 100 are classed as marine reptiles: extant marine reptiles include marine iguanas, sea snakes, sea turtles and saltwater crocodiles.
Crocodilians may be found swimming out at sea, but they can't live out there in the way that a marine turtle can.
Research, then write down what you know about them. For e.g, their lifespan, their weight, where you can spot them. etc
Sea snakes, or coral reef snakes, are a subfamily of venomous elapid snakes, that inhabit marine environments for most or all of their lives. Most are extensively adapted to a fully aquatic life and are unable to move on land.
Research, then write down facts about sea snakes, for e.g. how fast they swim, what do they eat or how long they live, etc.
Write down some interesting facts about sea turtles, like how long they live or how long can they dive, etc.
