Life and Habitat
The Antennariidae are benticoast fish that prefer sheltered zones, rocks, and wrecks. They stay completely still on the bottom. When they are disturbed, they move by walking on the bottom thanks to pectoral fins. They can also move forward by inhaling water that they expulse with their gill openings. Piscivorous species (fish eaters), frog fish “fish” their pray by waggling their fishing line. The pray is inhaled in a fraction of a second is the wide opened mouth of the animal. This is why they are also called Anglerfish. The females lay their eggs which stick together in a big gelatin like lump.
