Sea snakes are reptiles that have adapted to life underwater, they breathe air through valved nostrils, the valves close when they dive down and open when they come up for air, they usually stay down for 20-30mins before coming up for air.
These snakes also give birth to live young.
Although they have a poisonous bite that can paralyse prey they are not normally aggressive and are usually inquisitive to divers. Ref: https://en.wikipedia.org/wiki/Hydrophis_elegans
