The leaf scorpionfish (Taenianotus triacanthus) has many names; leaf scorpionfish, leaf fish, paperfish, and the three-spined scorpionfish. They are a non-migratory resident fish endemic to coral reefs, tropical waters, and rock crevices of oceans around East Africa, the Red Sea, north of Galapagos Islands, the Ryukyu Islands, Australia, tropical Indo-Pacific, and Hawaii. These reef fish have a wide variety of colors; green, red, pink, brown, yellow, and white. This fish has a fragile compressed body that resembles a swaying dead leaf. It has a large head and mouth, the big sail-like dorsal fin starts behind the eyes, while the anal fin has three spines. It holds venom in the spines along its back, weaker than other fish like lionfish. Its skin color and texture allow it to camouflage well and ambush its prey.
