Swimming snakes

Coral crevices along Niue’s shore harbour dens of writhing sea snakes, no more so than at Snake Gully. Here, snakes swim regularly to the surface to take a breath, then return to their lairs.

Produced by New Zealand Geographic

Sea snakes are extremely venomous, but their mouths are so small they can only bite a human on the ear lobes, or between the fingers.

How many can you count?
