This is a genuine Bullhead shark egg case or casing (Heterodontus francisci) Taken at tideline among boulders after juveniles hatched in Enseuada, Baja, Mexico Average 3-1/2? long x 1-1/2? wide . An egg case or egg capsule, colloquially known as a mermaid's purse or devil's purse, is a casing that surrounds the fertilized eggs of some sharks, skates, and chimaeras. They are made of collagen protein strands. Because they are lightweight, they are commonly washed up by the sea, often found at the strandline, the farthest point of the high tide. The egg cases that wash up on beaches are usually empty, the young fish having already hatched out. This is the exact item you would receive. -
