Species

See text

All the species within the genus Atys are herbivores. They occur in tropical and warm oceans and seas. They are cephalaspideans, part of the suborder of headshield slugs and bubble snails.

The genus was named after Atys, a king of Alba Longa, who was mentioned in ancient Greek texts.

DescriptionEdit

These snails have a shell which is very lightweight and translucent, with a sunken spire. The shape of the shell in some species resembles a bubble, and because of this, species in this genus are commonly known as Atys bubble shells or Atys bubble snails. (Several other shelled families within the Cephalaspidea are even more commonly known as "bubble shells" or "bubble snails", for example, the Bullidae.)

The anatomy of the soft parts of most species within this genus has not been studied, but it seems that some of the species in this genus can not reliably be discriminated on the basis of shell characters alone. Unfortunately however, a considerable number of the species were originally named from empty shells, and as a result, their exact identity may be problematic.
