Leathery soft coral ctenophores
Coeloplana sp.
Phylum Ctenophora
updated Oct 2016
Where seen? These tiny creatures are well camouflaged and often only spotted by the fine tentacles that they produce. Often overlooked, they are probably common on leathery soft corals on our shores. Their name is pronounced 'ten-nah-fours'.

Features: 1cm or smaller, body very flat with colour and patterns to match their host. Those seen so far were on large Omelette leathery soft corals (Sacrophyton sp.), often with many of them on one soft coral. The tiny animal produces two fringe tentacles than can be many times longer than the animal. It is used to gather food. The tentacles are stored in two large swellings on the animal.
