While most Sea Anemones and Sea Cucumbers are relatively harmless to humans a few do contain strong toxic substances producing quite severe effects. One of these Sea Anemones and Sea Cucumbers is the stinging anemone (Actinodendron plumosum), a blue-grey to light brown animal which can look somewhat like a fir tree.Found under boulders and coral, red bristle worms have numerous fine needle-like bristles which break off when they have become embedded in the skin, causing severe irritation.Although Sea Anemones and Sea Cucumbers are one of the safest animals on the reef to touch, the numerous white Cuvierian tubules, which some eject when irritated, contain a toxin which can cause blindness if it comes into contact with the eyes. This toxin may also be present on the skin so you should wash your hands after handling these creatures.
