Carnivorous snails

Snails have a single spiral shell. The shell usually sits high on the snail’s back and inside the shell cavity; it spirals inwards into a smaller and smaller tube. They use their large muscular foot for moving slowly across surfaces. The foot can be pulled into the shell when they are threatened. Snails belong to a very large group of molluscs called gastropods. 

Carnivorous snails hunt other marine creatures. Their prey is often slow moving and is often other molluscs. They have teeth that look like a wood rasp used to scrape the surface of seaweed. It is called a radula. Some carnivorous snails use their radula to bore holes into other molluscs and then suck their bodies out of their shell. The anus is near the edge of the shell at the top front of the body. The digestive organs need to be organised into the shape of the figure 8 so it can fit into the spiral shell. Carnivorous snails have a spout in the opening to their shells where they can poke out their sensory organs as they hunt.
