Evidence of the nasty sting that can be inflicted by members of the Cnidaria family which includes Jellyfish, Corals and Sea Anemones.

The culprit on this occasion was what i've tentatively identified as the Hairy Mushroom Anemone (Rhodactis Indosinensis), although that is far from certain. This species of small Anemone is very common at locations such as Sail Rock where it often forms vast colonies on the rock face.

Due to its small size and dull brownish appearance, it often goes completely unnoticed, however a short, sharp stinging sensation followed by a week or two nursing irritating, unsightly blisters should provide ample warning for future dives...
