REMARKS

Vision is very important to fish. Like all vertebrates they have well developed eyes and the optic lobe is the largest part of the fish brain.

Most land animals focus by changing the shape of the lens within the eye but fish achieve the same result by moving trheir lens in and out - rather like a camera.

Fish also do not need eyelids as their eyes are constantly bathed in water whereas we need out tears to keep our eyes moist.

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.
