Major Breakthrough in Evolutionary Biology Reveals Path from Simple to Complex Cells

A humpback anglerfish, known as the "black sea monster," was observed by the Condrik Tenerife research team off the coast of Tenerife, Spain, marking potentially the first daylight sighting of an adult Melanocetus johnsonii in the wild. Typically residing at depths of up to 1,500 meters, this rare fish was encountered while the team conducted pelagic shark research, according to the organization's Instagram post. Marine biologist Laia Valor reported that the team spent hours with the fish before it died. Its body was subsequently taken to the Museum of Nature and Archeology in Santa Cruz de Tenerife for further examination. Historically, adult anglerfish have only been found dead or as larvae at the water's surface, raising the significance of this sighting, Condrik Tenerife noted. Female anglerfish are distinguished by their bioluminescent dorsal appendage, which attracts prey. The sighting underscores the limited understanding of deep-sea biodiversity and the necessity for ongoing marine conservation efforts.
