Frogfish.
Antennariidae · also: Anglerfish (reef)
A frogfish is a reef magician — a lumpy, sponge-like ambush predator so well camouflaged that even sharp-eyed divers swim straight past it. It "walks" across the bottom on modified, leg-like fins and dangles a built-in fishing lure to draw prey close. Its strike is one of the fastest movements in the animal kingdom.
Size
Tiny to ~30 cm
Weight
Small-bodied; species range ~2–40 cm long.
Diet
Small fish and crustaceans — can swallow prey nearly its own size.
Lifespan
Varies by species; some reach ~10+ years.
Depth
Mostly shallow reefs and rubble.
Reproduction
Oviparous; many lay eggs in a buoyant mucus "egg raft" that drifts in the plankton.

Watch them responsibly
Look but never touch or "pose" them — disturbing a frogfish can push it off a productive ambush spot.
Lures prey with a modified fin tipped like a fishing rod and bait.
Its strike can take as little as ~6 milliseconds — among the fastest feeding strikes of any fish.
