They are carnivores and their diet mainly consists of:
* Small crustaceans: These include shrimp, crabs, and other small invertebrates that live on the ocean floor.
* Small fish: They may occasionally snatch up small fish that are unfortunate enough to wander into their territory.
The pancake batfish uses its modified pectoral fins as "legs" to walk along the seabed. These fins are also used to lure prey by wiggling them in a bait-like manner. They have a small, upward-facing mouth that is perfect for catching the small creatures that make up their diet.
Interesting fact: The pancake batfish doesn't actually "bat" at prey. It uses its modified fins to "walk" up to its food and then scoops it up with its small mouth.
