Frogfish are adept at disguising themselves in their ocean environment. Each species of frogfish has evolved different camouflage types to suit its surroundings; some resemble the texture and color of sea sponges, while others have long, waving extremities that can look like algae. One species can even change its coloring to help it blend in with red, pink, brown, or yellow rocks and sponges. Frogfish are solitary animals and prefer to live alone instead of in groups. They are territorial animals and often fight to defend their space against other frogfish or intruders.

Frogfish belong to the angler family and use a lure that dangles from their heads to attract prey. The seemingly harmless worm-like lure looks like a tasty treat to small fish and crustaceans. The frogfish will catch and eat unsuspecting prey when it comes close enough. Their prey includes crustaceans, small fish, and even other frogfish. To get around on the ocean floor, the frogfish uses its specialized pectoral fins, which act like legs. They can walk around instead of swimming, which adds to their stealth levels. Frogfish move slowly and carefully to sneak up on and ambush their food.
