Mitra (gastropod)


Mitra is a large genus of medium to large predatory sea snails, marine gastropod mollusks in the family Mitridae, the miter shells or mitre snails.
This genus is named after the ecclesiastical headgear, the miter, because of the shells' general shape.
These sea snails create shells that are considered attractive by shell collectors; the shells are solid, high-spired and are often colorful.

Description

The thick shell has a fusiform shape. The spire is elevated and acute at the apex. The aperture is small, narrow and notched in front. The columella is obliquely plicate. The outer lip is thickene and is smooth internally.
