The small pelagic snails of the family '''Hydromylidae''' ([[Alice Pruvot-Fol|Pruvot-Fol]], 1942) lack a shell (except in their early embryonic stage).They are carnivores, equipped with swimming parapoda (fleshy, winglike outgrowths), strong jaws and grasping tentacles, often with suckers resembling those of [[Cephalopod|cephalopods]]. |

Genus '''''Hydromyles''''' Gistl, 1848 |
|||
*''Hydromyles globulosus'' (Rang, 1825) |
|||
**Distribution: East Pacific, North America, Western Atlantic. |
|||
**Description: this pteropod sizes its prey with its radula. Contrary to most gymnosomatiids, this peropod has no proboscis and no hooks. It is also unique by having, close to the anal aperture, a sac for hatching its eggs. The larvae develop in this sac and are born as fully developed snails. |
