Whose work first identified the remora’s suction disc as a specialized attachment organ?
Quick Answer
Naturalists studying remoras in the 18th and 19th centuries described the dorsal fin transformed into a suction disc. That adaptation lets remoras hitchhike on sharks, turtles and other large animals.
The Full Story
Early naturalists described the remora as an odd fish that could cling to larger animals, but later anatomical studies showed how the trick works. The remora’s first dorsal fin has evolved into a suction disc with rows of movable plates. This lets the fish attach itself firmly to hosts while conserving energy and gaining transport, food scraps and protection. Remoras are a classic example of a fish adapted for a highly specialized way of life.
