Family HANLEYIDAE
Introduction
The Hanleyidae is a small family, found mainly in the Northern Hemisphere, although one species, Hemiarthrum setulosum, is circumpolar sub-Antarctic in distribution. This species broods its young to an advanced stage in the pallial groove.
The family is characterised by small, unslit insertion plates on at least some valves, and the spiculose girdle.
