Assimineidae Last updated September 30, 2025 Family of gastropods
Assimineidae is a family of small snails , also known as palmleaf snails , with an operculum , gastropod mollusks or micromollusks in the superfamily Truncatelloidea. Many of these very small snails live in intermediate habitats, being amphibious between saltwater and land; others live in freshwater.
Description The shell is small to medium large, more or less egg-conelike shaped. [ 2] The apertural margin is simple. [ 2] The operculum is in most cases horny. [ 2]
Species in this family are characterized by rudimentary cephalic tentacles , a trunklike snout , a foot with a groove and rudimentary to absent ctenidium (a comb-like respiratory apparatus). [ 4]
Taxonomy The following three subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005) :
