Toadfish is the common name for a variety of species from several different families of fish, usually because of their toad-like appearance. "Dog fish" is a name for certain species along the gulf coast.
Toadfish make up a notable portion of the dolphin's diet, approximately 13%. Scientific experiments have shown that the mating call of the toadfish alerts dolphin predators to the fish's location. Similarly, the sounds caused by the dolphin when hunting its prey alert toadfish to the location of the predators and cause the fish to silence their mating call. Male toadfish will reduce their mating calls by up to 50% when they hear the low sound of a dolphin's "pop".
