What do devil fish eat?

Devil fish is the common name of several different types of marine animals, so the answer to what they eat can vary depending on the specific species.

If you are referring to the giant pacific octopus (Enteroctopus dofleini), one of the largest species of octopus, they are known to be opportunistic predators and their diet can include a wide variety of marine animals. They typically feed on crustaceans, such as crabs, shrimp, and lobsters, as well as fish, including cod, flounder, and rockfish. They may also consume other cephalopods, such as squid and smaller octopuses. Giant pacific octopuses have even been known to hunt and eat sharks.

If you are referring to the manta ray (Manta birostris), a large species of ray, they are filter feeders and their diet primarily consists of plankton, small fish, and krill. They swim with their mouths open, filtering the water for these tiny organisms.

The diet of the monkfish (Lophius piscatorius), also known as the anglerfish or fishing frog, can include fish, crustaceans, and mollusks. They are ambush predators and use their long, modified dorsal fin as a lure to attract prey.

It's important to note that the diet of these animals can vary based on their habitat and the availability of food sources, and some species may have specialized diets or feed on a more specific range of prey.
