Bivalve shell

Beautiful burrower

These beautiful and highly-decorated bivalves have a triangular shape which gave rise to the old name Trigonia, but they have now been reclassified and given a new name, Myophorella.

This is a burrowing bivalve that lived in the sediment on the sea bed. Siphons extended through the sediment allowing the animal to suck water into the shell, filter it for food and then exhale, or squirt it back out again.

Our photos show the bivalve from different angles. The right-hand image is upside down – in life, the shell was orientated the other way around and the siphons extended from a gap between the shells.
