The red-lipped batfish, also known as the Galapagos batfish (Ogcocephalus darwini), is a unique species of fish found around the Galapagos Islands and off the coast of Peru. Its distinctive appearance has earned it the nickname "the fish with the bright red lips."

The red-lipped batfish belongs to the family Ogcocephalidae, which includes other species of batfish found in the Pacific Ocean. The closely related rosy-lipped batfish (Ogcocephalus porrectus) is found near Cocos Island off the Pacific coast of Costa Rica.
One of the most notable features of the red-lipped batfish is its bright red lips. The reason for this bright coloration is not entirely clear, but it is thought to play a role in mating or communication. In addition to its bright red lips, the red-lipped batfish has a unique morphology that sets it apart from other fish.
Batfish are not good swimmers; instead, they use their highly adapted pectoral, pelvic, and anal fins to "walk" on the ocean floor. The red-lipped batfish has a flattened body that is adapted to this walking behavior. It also has modified pelvic fins that resemble legs and allow it to move along the seafloor.
When the red-lipped batfish reaches maturity, its dorsal fin becomes a single spine-like projection. This projection is thought to function primarily as a lure for prey. The batfish lies in wait on the ocean floor, using its modified fins to walk into position, and then uses its dorsal fin as a lure to attract prey. Once a potential meal comes within range, the batfish quickly snaps it up with its large mouth.
The red-lipped batfish is typically found at depths of 3 to 76 meters (10 to 249 feet) and is most commonly encountered by divers exploring the waters around the Galapagos Islands. Despite its unusual appearance, the red-lipped batfish is not considered to be endangered.
In conclusion, the red-lipped batfish is a unique and fascinating species of fish that has adapted to its environment in a remarkable way. Its bright red lips and unusual morphology make it a popular subject for underwater photographers and divers, and its behavior is a testament to the incredible diversity of life that can be found in our oceans.
