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. This fish is mainly known for its bright red lips. Batfish are not good swimmers; they use their highly adapted pectoral 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). Like other anglerfish, the red-lipped batfish has a structure on its head known as illicium. This structure is employed for attracting prey.
INFO OF THE DAY
This is called a mirror or sequined spider. These spiders are all members of the Thwaitesia genus. Their most distinctive trait is the reflective silvery patches on their abdomen, hence the common name. The scales look like solid pieces of mirror glued to the spider’s back, but they can actually change size depending on how threatened the spider feels. The reflective scales are composed of reflective guanine, which these and other spiders use to give themselves color.
