The Red-Lipped batfish or Galapagos batfish (Ogcocephalus darwini) is a fish of unusual morphology found around the Galapagos Islands and off Peru at depths of 3 to 76 m (10 to 249 ft). Red-lipped batfish are closely related to rosy-lipped batfish (Ogcocephalus porrectus), which are found near Cocos Island off the Pacific coast of Costa Rica.

This fish is mainly known for its bright red lips. Batfish are not good swimmers; they use their highly adapted pectoral, pelvic and anal fins to "walk" on the ocean floor. When the batfish reaches maturity, its dorsal fin becomes a single spine-like projection (thought to function primarily as a lure for prey).

The Red-Lipped batfish species is a piscivore/invertivore, mainly feeding on other small fish and small invertebrates including shrimp, crabs, worms and mollusks.

The Red-Lipped batfish has a shorter disk perimeter but a higher fibre pectoral fin ray count. Regarding the number of scales along the lateral line, there are four to nine subopercular scales, six to nine on the cheek, usually. The red-lipped batfish has around 19-20 vertebrae. The red-lipped batfish reaches up to 40cm (15in) in length.

Red-lipped batfish have extremely bright red lips, which allows people to distinguish them from other batfish. Marine biologists believe that the bright red lips of the red-lipped batfish may be used to enhance species recognition during spawning.
