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.
What are the fish that attach to whale sharks?
Remoras — also known as suckerfish or whalesuckers — are strange, even for fish. They hitch rides with cetaceans, sharks and other larger creatures of the deep, attaching to them by means of a “sucking disc” that sits on their head like a flat, sticky hat.
Why do little fish stick to sharks?
In return, sharks do not eat pilot fish because pilot fish eat their parasites. This is called a “mutualist” relationship. Small pilot fish are often seen swimming into the mouth of a shark to eat small pieces of food from the shark’s teeth. Sailors even said that sharks and pilot fish act like close friends.
Does a remora hurt?
As long as the diver is covered by a wetsuit, the remora does no harm.
Are remoras edible?
The taste (mild, no aftertaste) and texture (firm white meat) were both excellent. In appearance and taste, the remora was similar to triggerfish. The downside: The yield, per fish, was surprisingly small, so you have to catch big ones.
Do remoras swim upside down?
In fact, it’s flipped upside down, using a specialized structure on the top of its head to get a grip. And it doesn’t just target sharks. Remoras go after all kinds of creatures, from sea turtles to manta rays to whales.
How big can a remora get?
Remoras are thin, elongated, rather dark fishes that live in tropical and subtropical oceans and seas. Remoras typically range from 30 to 90 cm (11.8 to 35.4 inches) in length, depending on the species.
Do remoras have teeth?
Remora has numerous small, pointed teeth that are slightly curved inward. Lower jaw is longer than upper jaw. Remora does not have swimming bladder. It uses sucking disk to attach itself to the body of other fish or marine creatures and to travel in the ocean.
How do remoras stick?
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 small fishes stick to whales?
Characteristics. Remora front dorsal fins have evolved to enable them to adhere by suction to smooth surfaces, and they spend most of their lives clinging to a host animal such as a whale, turtle, shark or ray.
Why do remoras attach to whales?
They discovered that remoras chose to stick to whales primarily at three places where they would face the least amount of resistance from the flow of water: behind the whale’s blowhole, behind and next to the dorsal fin, and above and behind the pectoral fin.
Where are remoras found?
Remoras are found in open seas at tropical latitudes around world. They are commonly found attached to sharks, manta rays, and other large fishes.
What are the fish that stick to turtles?
The most obvious hitchhikers catching a ride on a turtles shell are so called remoras. These fish use bigger sea creatures such as sharks, mantas or turtles as a MoneySlot taxi – even if occasionally a rather slow one.
Do fish touch you when snorkeling?

Why do remoras attach to turtles?
In such symbiotic relationship, remoras remove the parasites (such as copepods) found on the host turtle and clean sloughing epidermal tissue as well as ingesting scraps of food, feces, and small nekton and zooplankton.
