Undersea mystery: Why is this prey fish "kissing" its predator?


The razorfish (bottom) is surprisingly latched on to a lizardfish that can swallow it whole! What’s going on?

Anna Deloach (blennywater.com) recounts for us the mysterious observation:

Razorfish Bites


Lembeh Strait, Indonesia ~ Well the table is turned. I have seen prey in the grips of toothy lizardfishes before, but never this. What is going on here? From a distance I could see Ned watching what I thought was a lizardfish (quite a predator on the reef) trying to eat a razorfish. Then I realized the razorfish was firmly clamped onto the lizardfish – quite a reversal from the expected. Ned had a better angle and was able to get a shot that clearly shows it.

I contacted Dr. Gerry Allen for help with the razorfish identification – it is Cymolutes torquatus (and the lizardfish is Synodus dermatogenys) – and to ask if he had ever seen this behavior. He had not. I managed to get a tiny bit of video (below and on our BlennyWatcher Channel) and Ned shares this and other photos from our October 2012 trip to Raja Ampat and Lembeh over on our travel blog, marinelifeblog.com.
