Mermaid Purse

[Bogie]

I found a mermaid purse at Breakwater last weekend. This is the first one that I've found while diving. I think it is an egg case for a swell shark. The case is translucent and you can see the shark egg inside.
Let me know if I identified this correctly.

Wow that's really cool! I can't help with identification but thanks for sharing!

Yep, you got it buddy. Swell shark more likely per my research.

Bingo, swell shark.
