ABSTRACT
The sea snake is an efficient swimmer and is equipped with a paddle-shaped tail for this reason. It can submerge for 2 hours. They are inquisitive, and sometimes aggressive, especially if handled or trodden on. They are attracted by fast moving objects, e.g. divers being towed by a boat, and under these circumstances they can congregate and become troublesome. They are also caught in trawling nets, especially in the tropics. Land snakes may also take to the water, sometimes causing difficulty with identification. No land snake has the flattened tail.
