What is special about the remora fish?
The remora receives more than a convenient food source; the sharks protect them from predators and give them free transportation throughout the oceans. Remoras keep the waters clear of scraps around the shark, preventing the development of unhealthy organisms near the shark.
How did the remora evolve?
The remora fish is believed to have first begun attaching to hosts with rough surfaces, akin to sharks, after having evolved its suction disc nearly 32 million years ago. “The ‘how’ is from the dorsal fin, although the intermediate evolutionary stages aren’t known,” explained Flammang.
Do remoras have jaws?
When the remora reaches about 3 cm (1.2 in), the disc is fully formed and the remora can then attach to other animals. The remora’s lower jaw projects beyond the upper, and the animal lacks a swim bladder.
What is the relationship between Remora fish and shark in their habitat?
The relationship between remora fish and shark can be considered as mutualism. Remora attaches itself to the shark, to travel different parts of the sea by floating with the shark. It helps the remora fish to travel without burning energy. They also get to eat scraps of food dropped by the shark.

How do remoras suction?
They catch free rides by using a modified fin on their heads that acts as a suction pad to stick themselves to other fish that can be up to 20 times as long. Their suction pads are so powerful that remoras can stay attached to sharks and even dolphins when they’re leaping out of the ocean.
Why do remora fish attach to sharks?
