Wildlife Spotting

Looks like fish gills from something big like a grouper.

red drum?

Interesting!! do I see in the middle/top, 2 rows of lots of sharp teeth??

Ooooh- ok-- now I see! Yes iI agree it's probably the gill arches and rakers of a large fish. At first I didn't know what on earth it was! I thought it looked like a Weird creature from the old black and white Dr Who shows ! LOL)

bizarre and wonderful find! How large is it?

This reference might help. It has detailed images of gill structures including teeth. Check figure 66; Preliminary Fish Dissection http://www.artscape.us/aquaculture/fish_dissection/head_gills.html
