One of the critter kings, frogfish (aka anglerfish) are often photographed for a number of reasons - their various contrasting colours, textures and camouflages, their incredible hunting tactics and of course their down-turned mouths and muppet-like faces. Of course, the fact that they remain absolutely motionless for 90% of the time also helps the happy-snappers. (Photograph: Richard Smith)
