Maximum length: 55 mm

The pattern of this species is variable, but the body is often

in white to light yellow translucent tones,

of which a certain density of black spots predominates on the upper parts.

The elongated body consists of a head, which is called ‘head shield’ due to its shape.

There are no rhinophores, but a pair of chemical receptors located on each side of the head,

slightly behind the shield.

The head has four lobes and a row of sensory bristles on the front edge.

This snail, like almost all snails of this species, has a short blunt right tail

and a large fleshy, broad and elongated left tail.

It lives on sand, where it feels small organisms living on the ground with its bristles,

and then sucks them in with its mouth.

They come in different color variations, from completely black to black with white spots

and up to white specimens with black and yellow spots.

( as they had different colors ) it took a while.

Now they have been synonymized to four different species.

They are found in shallow lagoons on fine sand.

Diet: small flatworms.
