Mitridae, known as mitre shells, are a taxonomic family of sea snails, widely distributed marine gastropod molluscs in the clade Mitroidea.
Both the Latin name and the common name are taken from the item of ecclesiastical headgear, the mitre or miter, used in reference to the shape of the shells.
The dentition of radula (The radula is an anatomical structure used by mollusks for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. The radula is unique to the mollusks, and is found in every class of mollusk except the bivalves, which instead use cilia, waving filaments that bring minute organisms to the mouth.) in the Mitroidea is rachiglossate, with well-developed central and lateral teeth, both comb-like. Members of this family are predators(Ponder, Winston Frank; Lindberg, David R.; Ponder, Juliet Mary (2019). Biology and Evolution of the Mollusca. CRC Press. p. 1934. ISBN 978-1-351-11564-3.).
These sea snails are found in most warm and temperate seas.
Miters are common especially in the tropical Indo-pacific region. Most miters live in the intertidal zones, preferring sand, coral areas or stoney seafloors. Many are predatory mollusks and a few are scavengers.

MITRA MITRA SHELL
Mitra mitra, common name the episcopal miter. Thus the shell got its name from resembling a bishops miter. This species is a large predatory sea snail, a marine gastropod mollusk in the family Mitridae, the miters( Rosenberg, G. (2010). Mitra (Mitra) mitra (Linnaeus, 1758)).
Widespread in the Indo-Pacific, from East Africa, including Madagascar and the Red Sea, to eastern Polynesia. North to southern Japan, Wake Island and Hawaii, and south to Australia (Poutiers, J. M. (1998). Gastropods in: FAO Species Identification Guide for Fishery Purposes: The living marine resources of the Western Central Pacific Volume 1).
This species lives in intertidal and sublittoral zones, to a depth of around 263 feet. (Poutiers, J. M. (1998). Gastropods in: FAO Species Identification Guide for Fishery Purposes: The living marine resources of the Western Central Pacific Volume 1).
Mitra mitra are known to be carnivorous, an active predator that feeds on smaller gastropods and bivalves.
The maximum shell length for this species is around 7 inches, usually to 5 1/2 inches. Like in all Mitridae, the shell is elongate, somewhat fusiform, with a high spire. The aperture is elongate and narrow, and the outer lip is smooth and not lirate (grooved). Unlike other species of the genus Mitra, the spire is not strongly shouldered. The surface of the shell is smooth, with a few weak, spiral grooves towards the anterior end. The color is white, with spiral rows of large irregular orange or red spots (Poutiers, J. M. (1998). Gastropods in: FAO Species Identification Guide for Fishery Purposes: The living marine resources of the Western Central Pacific Volume 1).

MITRA PAPALIScommon name Papal/Pontifical Mitre
Mitra papalis are species of sea snail, a marine gastropod mollusk in the family Mitridae, the miters.
Mitra Papalis are present in India and in the western Indo-Pacific (Mitra papalis. Gastropods.com.).
These sea snails live on coral reefs and under rocks, from the intertidal zone to a depth of about 99 feet (LI Bao Quan, LI Xin Zheng - Report on genus Mitra with seven new record species from the Chinese seas).
Shells of Mitra papalis can reach a length of about 2 1/2 to 6 1/2 inches. The form of these large shells is similar to a Papal mitre (hence the common name). They are elongate to ovate, fusiform and smooth but without axial streaks on the surface. Sutural coronations are present. The aperture is moderately wide, smooth within. The shell surface is white, with small white nodules under sutures and with several rows of irregular bright red-orange or purplish blotches.(Mitra papalis". Gastropods.com.)
