The Ramora is an unusual fish.

It hitchhikes on other sea creatures using a sucker on its head.

So you can see them on whales, dolphins, sharks, turtles.

They stick to scuba divers.

They stick to boats.

They stick to other fishes and other ramaras.

Brooke Flamang is a comparative biomechanist at the New Jersey Institute of Technology and Rutgers

University. She says sticking to other animals is a pretty good strategy. They avoid predation

by sticking to large animals. No one's going to attack you if you're on a shark. And it's a food

source, many of them pick parasites off of the host they're attached to,

as well as eat bits of food that are flying by and poop. They also have the ability to

potentially meet other remorse for mating on the same organisms. But now her team has discovered

that the fish have another unusual quality. They're sensitive to touch, a type of touch previously

unknown in the fish world.

Up until now, we did not think that fish had the ability to sense touch in this way,

or to sense dragging and shear, which is, of course, going to be very important for a more
