While diving off the coast of Sulawesi, Indonesia, one diver captured video of a frogfish taking a stroll along the ocean floor. In the more than 1,000 dives that hobbyist diver Atsushi Sadaki claims to have been on, he says he's seen a few frogfish but never any moving in this way.

In the video, the frowny-faced fish can be seen hobbling forward on two front fins that splay out from the side of the animal's body. Frogfishes are "sit-and-wait" predators that pounce on unsuspecting smaller fish swimming past. Different species can be found throughout the world, but most tend to blend into their surroundings, meaning they don't really on speed or agility to find prey.
