To about 70 cm, flattened top to bottom, mottled to match coarse sand and rubble, with a broad flat head and a lacy fringed flap over the pupil that breaks up the one part of the animal camouflage cannot hide. The Indo-Pacific crocodilefish of Lembeh is a different species in a different genus; this is the Red Sea animal and the two are not interchangeable.
It lies still on sand or rubble beside reef and waits, taking small fish with a strike from a standing start. It does not move when approached, which makes it one of the easier subjects on a Red Sea dive and one of the easier animals to kneel on. The eye is the picture: get low, light it from the side, and the iris lappet shows.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
