Assimineidae is a

mollusks or micromollusks
in the superfamily Rissoidae. Many of these very small snails live in intermediate habitats, being amphibious between saltwater and land; others live in freshwater.

Distribution

The distribution of the Assimineidae is worldwide.[2] The oldest fossils are known from the Cenomanian aged Burmese amber.[3]

Ecology

Various species in this family occur in

estuarine habitats, in salt marshes and in freshwater. Some are terrestrial or amphibious
.

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]
