The smaller egg is a brown banded bamboo shark - just there for size comparison.
The big one is the egg case of a species I had hatch yesterday while I was setting up for MACNA this weekend.
Nope. I had mentioned the larger egg in a past thread when it came in. I was going to see if anyone remember me dropping a hint in passing. It's a Pacific benthic shark that will be the only one on public display in South FL when she graduates from her holding to the display tank in a few months.
