This is a Greenlip Abalone (Haliotis Laevigata). It typically measures between 10 and 20 cm in length, with a thick, slightly domed profile.

The exterior of the shell has a series of small holes along one side, which are used for respiration and waste expulsion. Concentric growth lines can also be observed across the surface.

The inside of the shell is lustrous and pearlescent, reflecting a range of iridescent colours. Its smooth interior makes it highly prized for decorative uses.

This species is found in coastal waters off Southern Australia, living on rocky reefs and primarily feeding on algae.

This shell was collected on the 21st of September 1915.
