Common tusk shell

Antalis vulgaris

Common tusk shells are slender marine mollusks with curved, tube-shaped shells open at both ends. They live buried in soft seafloor sediments and search through the sand for tiny prey.

Water

Saltwater

Soft sandy and muddy seafloors from shallow coastal water to deeper continental-shelf habitats.

Temperature

Range not established

A dependable species-specific wild temperature range was not found in the selected sources.

Size

About 3โ€“6 cm (1.2โ€“2.4 in) long

About the length of a paperclip

Lifespan

Not established in the wild.

Life expectancy varies with place, conditions, and what scientists have been able to observe.

01 ยท Signature adaptation

What does it do?

The animal usually stands partly buried in soft sediment with one end exposed to water. It has no obvious head or eyes and relies heavily on its captacula and radula while feeding.

Its superpowerFlexible captacula tentacles help it find and seize microscopic animals below the surface.

02 ยท Home coordinates

Where does it live?

From southwestern Britain and nearby Atlantic European coasts to the western Mediterranean.
