Manta Ray's relationship status: It’s complicated | S.E.A. Aquarium at Resorts World Sentosa
The symbiosis relationship between them is a commensalism relationship because the remora is getting its food and the shark gets no benefit. An overview is presented for a poorly documented relationship between reef vertebrates in Southwest . tached to whale sharks (Clarke & Nelson, ). In a commensal relationship, one organism benefits while the other is unaffected. By attaching itself to a leopard shark, a remora is carried along on the shark's.
The Aquarium is fortunate to have three resident Reef Manta Rays as well as a range of bottom and ocean dwelling rays. Reef Manta Rays have a smaller wing span of 3 to 3.
The Reef Manta Rays live in constant motion, using their powerful, wing-like fins to roam the ocean. 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.

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.
The Remora can be seen swimming below the Manta Ray waiting for left over krill. The remora's lower jaw projects beyond the upper, and the animal lacks a swim bladder.
They are commonly found attached to sharks, manta rayswhales, turtles, and dugongs hence the common names "sharksucker" and "whalesucker". Smaller remoras also fasten onto fish such as tuna and swordfishand some small remoras travel in the mouths or gills of large manta rays, ocean sunfishswordfish and sailfish.
Whale shark and remoras
The relationship between a remora and its host is most often taken to be one of commensalismspecifically phoresy. Physiology[ edit ] Research into the physiology of the remora has been of significant benefit to the understanding of ventilation costs in fish.
Remoras, like many other fishes, have two different modes of ventilation. Ram ventilation  is the process in which at higher speeds, the remora uses the force of the water moving past it to create movement of fluid in the gills.

Alternatively, at lower speeds the remora will use a form of active ventilation,  in which the fish actively moves fluid through its gills. In order to use active ventilation, a fish must actively use energy to move the fluid; however, determining this energy cost is normally complicated due to the movement of the fish when using either method.
As a result, the remora has proved invaluable in finding this cost difference since they will stick to a shark or tube, and hence remain stationary despite the movement or lack thereof of water. Experimental data from studies on remora found that the associated cost for active ventilation created a 3.
