Cool "shark purse" egg case!!! Great capture! Would love to have this added to my mission! Http://www.projectnoah.org/missions/332216008

My best guess is a clearnose skate egg case (Raja eglanteria) all other skates/rays/sharks in the area have live birth

Known as mermaid's purse--egg casing for sharks or skates

Egg case... either shark or skate

shark eggs?
