Bankia australis ( Calman, 1920)

Although resembling a worm this is a wood-boring bivalve and one of 4-6 species
that occurr in northern NSW. The image below shows the pallets that are used to
seal the entrance to the hole and are the most important identifying feature. A
very common species in estuaries on the east coast.



Below are close-ups of the bivalve shells used in boring the holes.
