Common Piddock or Pacific Mud Piddock

Zirfaea crispata

Description:

1-3" Bivalve in Southern California.

Habitat:

Mud and clay

Notes:

From Wikipedia "...one side of the piddock's shells has a set of ridges or "teeth", which they use to grind away at clay or soft rock and create tubular burrows. The shape of these burrows is due to the rotating motion of the piddock as it grinds the rock to make its home. The piddock stays in the burrow it digs for the entirety of its eight-year lifespan, with only its siphon exposed to take in water that it filters for food."
