The wartskin angler possesses many namesake wartlike protuberances and ranges widely in color. Growing to about six inches, the wartskin anglerfish will camouflage itself by changing colors to match its surroundings. This behavior is integral to its feeding method, which can only be described as “ambush.” These fish possess a specialized feeding apparatus called an illicium, which is really a modified spine. The illicium suspends a lure-like device called the esca in front of the anglerfish’s mouth, and when another fish takes the bait—BAM!—the anglerfish quickly makes it a meal. The wartskin anglerfish will not bother corals or most other invertebrates.
