I just returned from Costa Rica, diving the Gulf of Papagayo. On the last day I took the attached photos. At first I thought it was a goby but after looking at the picture I have my doubts. Can someone help me out with an ID please?

Sorry about the shop tag at the bottom, I did that for Scuba Santa pictures and forgot to turn it off when I exported these from Lightroom.

This is one of the fang blennies, possibly the sabretooth blenny, Plagiotremus azaleus.

Thanks Chris, I really appreciate your reply. It’s the first one I’ve ever seen.

No problem, a similar species is quite common around Sydney.
