Thais sometimes known as dog winkles, is a genus of medium to large predatory sea snails with an operculum, marine gastropod mollusks in the family Muricidae, the rock shells.

Contents

[edit] Habitat

Thais species live in rocky environments close to shore or in the intertidal zone.

[edit] Shell description

The shell is generally squat, short-spired, and solid, with a large body whorl. The sculpture varies according to the species, but it generally consists of ribs, riblets, nodules, and tubercles.

The shell length is from about 2 to 13 cm, depending on the species.

[edit] Life habits

These animals are predatory, like almost all the muricids.
