Symbiosis occurs when two organisms live together, and usually become Since both the shark and remora benefit from this relationship the shark Large colonies of barnacles are often seen on various whale body parts. Whale sharks are filter-feeding carpet sharks and are the largest living non- mammalian vertebrates. Remoras are fish that have a symbiotic relationship with . 4. Rate these relationships as commensal, mutualism, or parasitic: • Clownfish/ anemone. • Manta ray/cleaning fish. • Shark/remora. • Humpback whale/barnacle.

Manta Ray’s relationship status: It’s complicated

Most of the time they swim alone but they interact with other mantas when they are feeding in plankton rich currents, at cleaning stations where animals congregate to get cleaned, and during courtship. Manta Rays and the hitchhikers On a coral reef, animals live together and interact to form different types of relationships.

Commensalism is when one animal gains a benefit from a relationship without harming or helping the other animal.

Mutualism is when both animals benefit from the relationship. Manta Rays have relationships with a variety of hitchhiking animals such as Remoras and Cobias. The Remoras attach themselves to the mantas using oval, sucker-like organs that open and close to create suction. When the mantas feed, the Remoras will travel up to the mouths of their hosts and help themselves to leftover scraps of food.

A cord or rope is fastened to the remora's tail, and when a turtle is sighted, the fish is released from the boat; it usually heads directly for the turtle and fastens itself to the turtle's shell, and then both remora and turtle are hauled in.

Smaller turtles can be pulled completely into the boat by this method, while larger ones are hauled within harpooning range. This practice has been reported throughout the Indian Oceanespecially from eastern Africa near Zanzibar and Mozambique[11] and from northern Australia near Cape York and Torres Strait.

Some of the first records of the "fishing fish" in the Western literature come from the accounts of the second voyage of Christopher Columbus.

However, Leo Wiener considers the Columbus accounts to be apocryphal: Echeneis In ancient times, the remora was believed to stop a ship from sailing. In a notable account by Pliny the Elderthe remora is blamed for the defeat of Mark Antony at the Battle of Actium and, indirectly, for the death of Caligula.

Because there are few consequences for the neutral party in either direction, commensal organisms are also likely to be generalists, since they are not evolving in concert with their hosts like in a mutualistic relationship. This generalism is seen in our first example: The fish pictured above is a remora, a group of eight species spread over three genera.

This small taxonomic family of saltwater fish would be unremarkable if it were not for their distinctive adaptations for commensal symbiosis. The first dorsal fin the fin on the back closest to the head has been modified into an oval-shaped sucker, with slat-like structures that allow the fish to attach to larger organisms using suction.

In fact this particular individual fish, a resident at the Shedd Aquarium in Chicago, was my inspiration for choosing the topic of symbiosis for this season. They will attach to whales and dolphins, sharks and rays, or any other large fish or reptile they can find.

The remora at Shedd most commonly attaches itself to the sea turtle in its tank. The individual sea turtle is also interesting because it does not have full control of its buoyancy.

There is an air pocket in the rear of its shell that makes that part rise up above the head. What benefit does the remora get out of this relationship?

By attaching to a larger organism it reduces the energy required for transport and ventilation of its gills for breathing. It also provides a small amount of potential shelter from predators though there have been instances of the remora becoming prey to its host when it attempts to attach to a shark. Riding along with another animal also gives the fish access to a ready source of food. Initially, it was thought that remoras would feed off of meal scraps from their hosts.
