Episcopal Mitre

Overview

The Episcopal Mitre (Mitra mitra) is a large, predatory sea snail widely distributed across the Indo-Pacific region. It is a common inhabitant of tropical reefs and sandy environments, easily recognized by its distinctive, colorful shell pattern.

Distribution & habitat

This species is found throughout the Indo-Pacific, ranging from East Africa and the Red Sea to eastern Polynesia, and from southern Japan down to Australia. It typically resides in intertidal and sublittoral zones, often burying itself in sandy or silty sediments during the day. While it can be found in shallow waters, it is also known to inhabit depths of up to 80 meters.

Appearance

The shell is elongate and spindle-shaped with a high, pointed spire. Its surface is generally smooth, featuring a white base color adorned with spiral rows of large, irregular orange or red spots. Unlike some other members of its family, the spire is not strongly shouldered. The aperture is narrow, and the columella typically displays four to five distinct folds.

Biology & behavior

Mitra mitra is primarily nocturnal. During the day, it remains hidden beneath the sand, often leaving behind large tracks as it moves. At night, it emerges to hunt, utilizing a specialized olfactory organ to locate prey. It lacks an operculum and possesses a relatively small head with a pair of elongated tentacles that bear eyes at their outer edges.
