Laginiopsidae is represented by a single species (Laginiopsis trilobata), itself known from only a single specimen. This was one of several species described by the French malacologist Alice Pruvot-Fol. Like other Gymnosomata, the Laginiopsids are likely carnivorous, though nothing about the species' feeding habits and life history are recorded.[1]

The body of the single species is rounded with large swimming parapoda (wings). The various tentacles, suckers, jaws, and radula typical of other Gymnosomata are all absent in this family (the lack of a radula being particularly distinctive). The head has a long proboscis tipped with the mouth and three fleshy lobes. [1]
