What is "haleciidae"

The Haleciidae are a hydrozoan family of the suborder Conica. Their hydroid colonies emerge from a creeping hydrorhiza and usually form upright branching colonies, although some species' colonies are stolonal. Their gonophores are typically sporosacs, growing singly or bunched into a glomulus. They remain attached to the hydroids or break off to be passively drifted away; in a few, the gonophores are naked.

Some enigmatic actively swimming medusae have been tentatively placed in this family as a kind of " wastebin taxon". Should their associated hydroids turn out to belong elsewhere, they are to be moved to that family and genus. The relationships of this fairly small but distinctive radiation to other conican Leptomedusae are not well understood at present; the Lovenellidae, however, typically turn out to contain the hydroid stage of medusae placed in the Haleciidae.
