A heavy mottled scorpionfish with a fringe of skin flaps hanging off its lower jaw, sitting on coral rock and not moving. Twenty-seven centimeters (11 in), and it belongs to this sea and the 🌊 Gulf of Aden alone.
The beard is camouflage where camouflage is hardest. A straight jaw line is the one edge that reads as an animal against textured rock, and the flaps break it up completely; the same trick appears in the fringes over its eyes and along its flanks.
It hunts by absolute stillness, which is unusual even among ambush predators. A scorpionfish will let a diver approach to within centimeters rather than move, because moving is what gives it away - and that is why so many stings are to hands and knees rather than to anything else.
The strike takes about fifteen milliseconds. The mouth opens, the head expands, and a small fish that was swimming past is inside before its nervous system has registered a change. Everything else about this animal is arranged around that one movement.
