Nudibranch Sea Slugs
The nudibranch sea slug family may look beautiful, but those bright colours and patterns are the creature's way of warning you it contains a very potent poison.

With no shells for protection, nudibranchs have had to develop a vast armoury of alternative defences. Some species can produce a distasteful noxious secretion to deter potential predators, such as fish. Other species feed on sea anemones, hydroids, jellyfish, soft corals and hard corals and are able to store special stinging cells called nematocysts from these animals food they eat. When attacked, they can discharge the stinging cells to deter their predators. Other nudibranchs use camouflage to avoid detection. Most nudibranchs have intricate and vivid colour patterns to advertise to predators that they are dangerous to eat. There are about 3000 nudibranch species and believe it or not, new ones are being identified daily.
