REMARKS

"Nudibranch" meaning naked gills are marine snails that have no shell. The largest species of nudibranchs grow up to 40cm but most are smaller than 10cm.

All nudibranchs are flesh eaters (carnivores). They feed on other invertebrates such as sponges, soft corals, anemones, seapens and hydroids.

Each nudibranch is both and female which can produce sperm and eggs. To mate the two come together side by side and pass sperm sacs through a tube in their neck to each other. They then go their own way and lay egg masses that contain millions of eggs.

How Do Fish Communicate
The colour of fish is one of the main forms of communication. With most fish lacking any form of vocalisation, the only way to communicate is by sight. This is very important at breeding time and camouflage is another aspect which makes them less vulnerable to predators and also helps them blend into the corals.

Low Isles, Great Barrier Reef Island

Sail on Wavedancer to an idyllic island. Snorkel, view turtles, explore the island with a marine biologist or just relax under a thatched umbrella.

Looking forward to spending the day with you
