Halftide, as it is known to locals, is renowned for the olive-headed seasnake. Divers are almost guaranteed seeing a snake or two here. Although its venom is deadly poisonous, the species is harmless—their mouth is so small that they could only bite the webbed skin between your fingers.

The olive-headed seasnake is the favourite prey of the osprey. Osprey nests can be seen on many of the high rocky headlands of the islands. The nests can survive cyclones and some are decades old. They are often full of the skeletons of hapless seasnakes.

Halftide has about 36 coral species.
