Species Overview

Anglers & Frogfish are bizarre and interesting reef compatible fish. These ambush predators come in a variety of colors and patterns that allow them to blend perfectly into their reef environment.

They also have a fleshy, specialized appendage (the esca) that extends from the front portion of the dorsal fin. This appendage can be moved and bobbed to lure unsuspecting prey close enough to be gulped down. Frogfish have jaws made of thin and flexible bones that allow them to swallow large prey, and large expandable stomachs. These adaptations make it possible for them to swallow and digest prey as big as their own body!

Anglers & Frogfish can grow to be as large as 8 inches depending on the species. The largest species are the Giant Frogfish (Antennarius commersoni), the Shaggy Anglerfish (A. hispidus), and the Patterned Anglerfish (Antennarius sp.). Smaller species, such as the Warty Anglerfish (A. maculatus) only grow to be about 4 inches long.
