Ogcocephalus vespertilio

It lives on the ocean-floor, covered in sand. The fish are flat, resembling pancakes. It preys on bottom-dwelling invertebrates.

These fish are nocturnal, and typically prey on other bottom-dwelling organisms in the early morning.[2] The Brazilian Batfish stays stationary and hidden in rock holes and other small crevices during the day.[2]

While active, it searches for prey walking along the bottom with the help of its specialized paired fins, with the illicium protracted and oscillating or exploring the substrate. The prey are either snapped up from the bottom, after visual detection, or dug out with use of the mouth and rostrum. It feeds on crustaceans (hermit crabs, true crabs, shrimps, amphipods, porcelain crabs, isopods and mysid shrimps), molluscs (snails, sea slugs and clams), polychaete worms (mostly Errantia) and echinoderms (sea urchins and brittle stars). [2]

This species can be found in the aquarium trade.
