Fabulous collection of treasures. I wonder if the shark egg case belonged to a relative of the little chap (Port Jackson shark) the fisherman caught at our local marina a few days ago. http://365project.org/onewing/365/2017-03-10
@pusspup Yes he let it go. He was so surprised to catch it in the first place and I just happened to be walking along the breakwater when he caught it and took the photo.
