Triton snails
Family Ranellidae
updated Oct 10

Where seen? The commonly seen triton snail is rather small and boring. It is usually found under stones on our Northern shores.

Features: The larger species of triton snails are better known. They can grow to 50cm up to 1m long! Many of them have a hairy covering on the shell. The operculum is made of a horn-like material and is thick and brown. They are found in sandy and rocky habitats, many are only found offshore in deeper waters. They were previously placed in Family Cymatiidae.

What do they eat? Some large tritons eat living sea stars and sea cucumbers. Others may prey on other snails and on clams, or ascidians. The prey is often first paralysed with an acidic salivary secretion before it is devoured.

Human uses: In the past, large specimens were used a trumpets. Thus another common name for theirs shells is Trumpet shells.
