Tritoniidae

These nudibranchs occur worldwide in warm and temperate seas and in the coldest waters and deep sea, wherever the octocorals which they eat are found. ==Ecology==

Members of the family Tritoniidae feed on octocorals, including sea pens, alcyonarian soft corals, and gorgonians, often being cryptic in shape and colouration upon them. They share this trait with the Arminidae which were previously thought to be only distantly related, but have been shown to be closely related to the Tritoniidae by a recent study. ==Taxonomy==
