Slit Sea Snail

The Slit Sea Snail (Perotrochus caledonicus or Mikadotrochus caledonicus) is a marine (saltwater) gastropod mollusc in the Pleurotomariidae family of slit snails. Gastropod means stomach-footed.

The Slit Sea Snail has gills and an operculum. The operculum is attached at the muscle to the upper surface of the back part of the snail’s body (called the foot). Its shell is conical with whorls (spirals) of orange-brown and yellow-cream. It has a slit (hole) which is small. 

It grows to 3-5 centimetres (1-2 inches) tall.
