Five Frogfish Facts

Megan Denny11 March, 2014

Frogfish are masters of disguise. Spot one during a dive and you will win the admiration of every diver in your group – especially photographers. Frogfish, a type of anglerfish, have a textured exterior that aids in their camouflage. While they do not have scales, their amazing ability to camouflage themselves serves as protection from predators. Frogfish vary in color and often have unique spines or bumps that change with their surroundings.

Here are some more interesting frogfish facts:

1. Unlike many animals that use camouflage as a defense from predators, frogfish mostly use their abilities to attract prey.
2. Frogfish have a modified dorsal fin that has a retractable lure resembling a shrimp, which is used to attract their prey. If their lure is eaten or damaged it can be regenerated.
3. Frogfish are carnivores. They eat fish, crustaceans and even other frogfish.
4. A frogfish’s mouth can expand to 12 times its resting size. This allows it to catch all sorts of prey.
5. Because frogfish lack a swim bladder, they use their modified pectoral fins to walk, or even gallop, across the seafloor (check out this great video of a frogfish in action).FrogFish yawningBy Steve Childs (Flickr: Painted FrogFish yawning)

There are many fish in the sea that use camouflage, but the frogfish is a real treat to see. Frogfish can be found in tropical and subtropical oceans and seas off the coasts of Africa, Asia, Australia and North America. Next time you take a dive in one of these regions take a closer look at the reef.
