Family  Cavoliniidae





The Cavoliniidae, one of the groups of sea butterflies, live in the plankton, remaining in the water column throughout their entire life. They swim by flapping two parapodia, giving a butterfly effect. They have a thin uncoiled shell a few millimeters in size, variable in form from needle-like to triangular to bottle-shaped or globular. They are most abundant in tropical or subtropical waters and are usually collected in plankton trawls. Ten species of this family are recorded from NSW.
