Mollusca – Gastropoda


The ear-shaped shell of an abalone is hard and rough on the outside to protect the animal from predators, and smooth and shiny on the inside to protect the soft body from damage. Water is drawn in near the front of the shell, passes through the gills, and leaves through the row of respiratory holes near the edge of the shell. Abalone are herbivores – they feed on algae mainly at night and hold on tightly to the rocks during the day.

Did you know?

An abalone does not have a blood-clotting agent and can therefore bleed to death if it is damaged or injured when being removed from a reef.
