Dentimitrella pulla (Family Columbellidae)

Long Dove Mitre

Distribution:

The Long Dove Mitre has a southern Australian temperate distribution. It ranges from NSW, Vic, Tas, SA and southern WA. (NSW, VIC, TAS, SA, WA)

Features:

The Long Dove Mitre has a small, pointed, lengthened, solid shell, with mildly rounded whorls, and little sculpture. It grows to 15 mm in length. The sculpture consists of spiral grooves near the anterior end adjacent to the aperture. Its aperture has a long oval shape, about half the height of the shell length. The canal is short and at an angle. The acutely angled, thickened outer lip is sculptured with strong dentate or tooth-like bumps. The columella has a flat groove that is marked with teeth-like bumps. The operculum is small and made of horn-like material.

Its shell colour is quite variable. It is often cream in colour with dark brown spots above the sutures (whorl joins) and has lighter reticulated markings between. Inside the shell is light brown, with a while columella.

Ecology/Way of Life:

The Long Dove Mitre is commonly found at low tide levels, buried under stones, or in pools on algae and seagrasses.

Interaction with Humans/Threats:

The Long Dove Mitre is widespread across southern Australian shores and probably isn't under threat from human interaction.

Other Comments:

Dentimitrella pulla, Gascoin, 1851. Denti comes from the Latin dens or dentis, meaning a tooth. This refers to the bump like teeth inside the aperture of this genus. Mitrella may come from the Greek word mitra, meaning a fillet, but also describes the tall, cleft hat worn by archbishops and bishops. Pulla is the Latin word for hen.
