This week features one of the oddest members of the fish family is the frog fish. From just looking at its picture, you can tell that it has a unique adaptation: it has feet! Well, not really. They use their pectoral and pelvic fins to walk along the sea floor. Mainly a benthic animal, waiting for a snack to come along, they usually make a run or trot to capture dinner. Sometimes, they sit so still that they have been mistaken for sponges. Some species of frogfish have a unique lure, called an illicium, right above their mouths that they use to lure unsuspecting snacks into its clutches.

Watch a video of them walking around! 

Can you find the fish? You can see how they can be easily mistaken for an inanimate sponge! Courtesy of Dr. Jessie Sanders.
