Picture of the Week, Marble Mouth Anglerfish


Marble Mouth Anglerfish

This week’s AquaNerd Picture of the Week is a reader submitted photo from our friend Louis-Pierre Rich. In the image, an elaborately camouflaged Marble Mouth Anglerfish (Lophiocharon lithinostomus), which faces the camera in case you can’t tell, is laying in wait for an unsuspecting prey fish to swim by so that it can be snatched out of the water column and into that very expandable mouth. This fish obviously blends in well with its surroundings, as it looks like a piece of the live rock covered in purple and green algae. Heck, even the fish’s nares (scientific jargon for nostrils) look like tiny sponges. This anglerfish, and most others, use their dorsal fish to lure in prey close to its mouth so that it can rapidly suck up anything big enough to fit.
