Little Wing Pearl Shell

Electroma papilionacea

Description:

A bivalve with paper-thin shells and about 40 mm wide. It had broken orange bands radiating from the umbo (where the valves are hinged). A very fragile specimen that was surprisingly intact despite being blown about in the wind.
The slightly flared part of the shell near the umbo ( on the Lt side in Pic 1) is called the auricle or wing, giving the species it's common name.

Habitat:

Spotted in the high tide area of the beach along with other shells & washed up sea weed - Rickett's Point ( Port Philip Bay)
Occurrence record:

The bivalve feeds on organic matter on or near the sea floor from 1 to 30 mts.
