Mermaid's Purse Display

This 6" X 5" display features an egg case from the Little Ray (Leucoraja erinacea).  Also known as “Mermaid’s Purses”, the egg cases of rays feature long, flexible “horns” at the corners that catch onto marine plants and corals.  The embryo develops within the case and then escapes by pushing open one end.  Empty cases often wash up onto beaches.
