Flabelligobius sp. ; Caudal fin ; detail

This goby has a big round graceful first dorsal fin.
If you want to see it, please refer to vol.64.
This species is rather shy.
When a predator approaches,it hides its caudal fin in the burrow
first. So there would be few who has ever seen the detail of the spread caudal fin.
