Antalis vulgaris, commonly known as the common tusk shell, is a species of scaphopods mainly encountered on sandy bottoms from 5 to 1000 meters depth.[1]

Description

[edit]

Antalis vulgaris is a small mollusc of 3 to 6 cm length with a characteristic elephant tusk shape. Its shell is opaque white and displays closely spaced longitudinal striations on the posterior portion. The anterior aperture (thinnest end) is circular and is occluded by a septum with a central pipe bearing a circular orifice.[2]

Distribution

[edit]

The common tusk shell is found from south-western United Kingdom to western Mediterranean.[3]

Diet

[edit]

The species stands vertically in soft grounds and search the sand with specific adhesive tentacles (captacula) for small benthic species such as foraminifera.[3][4]

Reproduction

[edit]

Separated sexes. The fecundation is external and gives rise to planktonic larvae called trochophore.[3]

Similar species

[edit]
  • Antalis entalis (Linnaeus, 1758) is smaller (4cm), has a pyriform-shaped anterior orifice and has no longitudinal striations.
