Description
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
The common tusk shell is found from south-western United Kingdom to western Mediterranean.[3]
Behaviour
Diet
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
Separated sexes. The fecundation is external and gives rise to planktonic larvae called trochophore.[3]
