REMARKS

There are 15 types of sea snakes that live in the water of the Great Barrier Reef. The olive sea snake is most commonly encounted by divers.

They breathe air and have valved nostrils so that when they dive down they do not get a nose full of water. They usually stay under water for 20-30 minutes, but they can stay down for over 2 hours before coming up for air.

They have a poisonous bite that paralyses their prey. They feed on fish, fish eggs, burrowing eels and even stonefish.

We receive an updated weather report directly from our crew living at Agincourt Reef at 7.30am each morning. Please call for further information, such as cloud cover, as often weather conditions will be different at the reef to the mainland.

Fish and Colour
One of the most important reasons is communication. With most fish lacking any form of vocalization, the only way to communicate is by sight. This is very important at breeding time and camouflage is another important aspect which makes them less vulnerable to predators and also helps them blend into the coral environment.
