Buccinum undatum

It is a big sailor snail, often brown. He eats the corpse of your seafish because he is a scavenger.

The Buccinum Undatum snail is a marine gastropod mollusk belonging to the Buccinidae family. It is commonly called "snail-bourse".

It measures on average between 5 and 8 cm long, with a spiral and solid shell, of a gray-blue-brown color. The shell is characteristic of this species, with longitudinal stripes and pronounced transversal streaks.

The snail-bourse has an elongated head, with short and wide tentacles, covered with small eyes. His mouth has two hooks, called "palps", used to catch and shred his food.

It feeds mainly on bivalve molluscs, which it destroys by piercing their shell thanks to its palps. It moves slowly on the seabed using its large ventral base and its muscular foot.

The snail-bourse is a common species in the cold waters of the North Atlantic and the North Sea, where it reproduces in summer. Females lay eggs in large quantities, which hatch in about a week to give birth to larvae called "trochophores". These larvae develop by forming a spiral shell, and reach their sexual maturity in 1 to 2 years.

Unknown.

We don't know anything about his reproduction, he can lay eggs in clusters, if there is a couple.
