Remora Fish
Remora are a tiny type of fish that measures one to three feet long. Their front dorsal fin sits like a suction cup at the top of their heads, allowing themselves to attach to a passing shark. The remora fish usually attach to the shark’s underbelly and eat scraps of prey dropped by the shark. They benefit the shark by eating parasites on the shark’s skin and mouth that would otherwise irritate and harm the shark. The sharks protect the remora fish from predators and give them free transportation across the ocean. Sharks seem to understand the benefits of “befriending” remoras, and have been observed slowing down to allow remoras to suction to them.
