Remora - Wikipedia
Three symbiotic relationships. Mutualism is when two organisms benefit from each-other. An example would be the Remora and a Manta Ray. The most common of these relationships is that between remoras and their Learn more about Manta rays symbiosis and cleaning stations and social behavior. Find out the relationship status of the Manta Ray and other sea creatures that hang The Remoras attach themselves to the mantas using oval.
It visits a small cleaner fish, like the bluestreak wrasse, that gently eats away surface parasites from skin, mouth, and gills. The resident fish doctor and dentist on the reef is the bluestreak cleaner wrasse Labroides dimidiatus. With an easily identifiable bright blue stripe and stereotypical behavior, the bluestreak attracts larger fish, like the reef lizardfish, to its cleaning station. As it makes a meal out of the larger fish's parasites, the bluestreak gently tickles its customers, a behavior that seems to bring them back again and again.
Sponge crabs Dromiidae family avoid predators by carrying a disguise with them at all times. Their posterior legs are modified for grasping, and the crabs use them to carry live Halichondria sponges on their backs.
Since the sponges are toxic to most potential predators, the undercover crab doesn't have to worry about being attacked and can concentrate on more important things, like finding food. Many sea sponges have evolved chemical weaponry for use against other sessile organisms in the never-ending battle for space on the reef.
Since the compounds tend to be distasteful and often toxic to predators, the sponges avoid most predation.

Sponge crabs exploit this defense by carrying live sea sponges on their backs. And the sponges may benefit, too: By living atop a crab, they no longer have to battle for space. Myths about divers being caught and eaten by giant clams Tridacna gigas still abound. The clams, though immense up to three feet across and weighing more than poundsare not man-eaters.
In fact, they are filter feeders that strain tiny food particles from the water. They get whatever additional nutrition they need from symbiotic algae, such as zooxanthellae, similar to those found in reef-building corals. Zooxanthellae are microscopic algae that live within the tissues of a variety of host animals, including giant clams. Like all plants, zooxanthellae use energy from sunlight to make their own food by a process called photosynthesis.
Excess food leaks out of the algae and into the filter-feeding clam, which relies on the algae's extra energy to survive. Because zooxanthellae make food most efficiently in fairly shallow, well-lit waters, giant clams are most abundant there too. Jellyfish are soft-bodied, free-swimming animals closely related to the corals.
Manta Ray with Remoras
Most jellyfish are predators, using the tentacles that drape from their floating bell to ensnare and paralyze prey. A few species of so-called upside-down jellyfish Casseiopea medusaehowever, have literally "flipped their lids.
Zooxanthellae are microscopic algae that live within the tissues of host animals, including hermatypic corals, giant clams, and upside-down jellyfish. The jellies may be the best hosts of all because they can swim to a depth where the zooxanthellae have optimal sunlight levels.
The tiny plants cover the tentacles of the jellies, making food by photosynthesis and releasing whatever they don't need right into the jellyfish's tissues.
Manta Ray and Remora by Alexis Garr on Prezi
Every living organism eventually dies, whether killed by a predator, a disease, or just "old age. Not surprisingly, a large group of organisms, called detritovores, have evolved in a way that lets them take advantage of this resource in every environment. For example, stalk-eyed ghost crabs eat carcasses, such as dead terns, that wash up on cay beaches.
In turn, living terns Sterna spp. 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. Concerning the latter case, remoras were used as an outgroup when investigating tetrodotoxin resistance in remoras, pufferfish, and related species, finding remoras specifically Echeneis naucrates had a resistance of 6.
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.
It is defined as any permanent or long-lasting association between two or more different species of organisms.
Each relationship has two participants, generally a larger one named the host, and a smaller one referred to as the symbiont. On the other hand, the symbiont can offer an immense variety of attributes from specialized biological processes to basic cleaning functions.Bond Between Sharks and Remoras 1
There is definitely a much larger variety in what the symbiont provides its host. Overall, symbiotic relationships are categorized by the type off association, level of intimacy, and the overall level of dependence. Types of Symbiosis Like any good relationship there are many ways to make it successful, and as such there are three main types of symbiotic relationships. Think of every time you have seen a goby standing guard over its pistol shrimp partner.
In this relationship, the goby gains the benefit of having a burrow to live in and seek shelter from predators. Anemones benefit from having a very territorial protector that cleans the tentacles from food scraps and the anemonefish gains shelter and food scraps from the association.
Note that it is fine line between mutualism, commensalism and parasitic relationships since the slightest negative impact on the host will turn the relationship into a parasitic one. The most common of these relationships is that between remoras and their various hosts.
Manta Ray’s relationship status: It’s complicated
Remoras attach their suckers to bigger pelagic creatures like sharksdugongs and sea turtles and benefit from the protection, transport and food scraps of their ride. Other commensal relationships include emperor shrimps finding shelter and transport on various nudibranchs and sea cucumbers and the small crabs and shrimps gaining protection and transport on their host fire urchin.
Parasitic relationships are harmful for the host, who can even die from it. One example of a non-fatal parasitic relationship is the parasitic isopod crustacean that attaches itself on fish flesh to gorge from it.
