About the genus Pupa

Note the head shield spilt into two large flaps by the medial groove. These flaps cover the opening to the mantle cavity and so protect it from becoming blocked with sand when the animal is burrowing. Like all species of Pupa the animal is relatively small and colourless, and it feeds on polychaete worms.
