The commensalism between a shark and a remora benefits the remora and does not harm the shark. The remora is able to obtain food from the shark as it drops food while it eats.
An example of commensalism in an ecosystem is the relationship between a remora fish and a shark. The remora fish attaches itself to the shark's body and benefits by getting a free ride and access to food scraps left by the shark. The shark is not affected by the presence of the remora fish. This demonstrates a one-sided relationship where one species benefits (the remora fish) while the other is neither harmed nor helped (the shark).
REMORA IS SMALL AND IS NOT REALLY HARM full then shark but shark doesnt and never eats remora . and remora never eats shark ( this is th e answer i am a diver that's why i think it is correct
No a shark doesn't benefit from the relationship with a remora. When two organisms benefit from their relationship that is known as mutualisim. A remora lays on the surface of the shark catching all the leftover food from the shark. The shark doesn't benefit or get harmed by the remora and this relationship is known as commensalism. There is also parasitism which is when one organism benefits and one is harmed.
The remora sucks on to the shark using a pad on its back like a suction cup. It can breathe because as the shark swims through the water it pushes the water through the remora's gills. Which lets it absorb the oxygen out of the water to breathe.
Remora fish and sharks have a mutual symbiotic relationship. Studies have shown that there is a bacteria that grows on the sharks that is potentially deadly to a shark. The remora fish eats this bacteria and gets a meal. The remora fish also gets transportation with a lesser energy cost.
Remoras attach themselves to the shark and eat the leftover food remains that they can find. This would fall into the commensalism symbiotic relationship, because the remora is getting its food, and the shark gets no benefit. There are other studies that suggest that the remoras clean parasites from the shark's teeth and perhaps skin. If this is true then it is a mutualism relationship. Remoras eat the parasites off the underside of the shark to keep it healthy and alive. Plus the Remoras get a free meal and protection. A mutualistic symbiotic relationship. the pilot fish clean the shark's teeth and skin, and the shark protects them The remora fish attach to the shark's belly and eat the malignant parasites off it. Also remoras can stick to other organisms such as whales, other big fish and maybe also crocodiles. This would still fall into the category of commensalism.
Sharks do not tend to mind these parasites sticking to them all the time, remoras just stick to sharks to either get around or to eat the dirt off them. Remoras are streamlined so that it will not affect the shark's swimming.
Mutalistic Relationship, both are benefiting. The shark is getting cleaned and groomed while the remora is getting fed and transported. Remoras have suction pads that can stick onto the shark. The Remora gets transported by the shark without the shark attacking.
Commensalism, which is a form of symbiosis in which neither party does the other much good or much harm, is rather rare and hard to declare. The usual example is that of the shark and the remora. But although the remora doesn't feed on the shark (which would make it a parasite), it does hamper the shark by increasing the drag on it. If the remora helped the shark find its food, it might be in a case of mutualism, but it doesn't, so it's a "commensal" (the word means "at the same table") almost be default.
It appears there is a typo in your question. Perhaps you meant "commensalism"? If so, commensalism is a type of symbiotic relationship in which one organism benefits while the other is neither harmed nor helped. An example is a remora fish attaching itself to a shark to feed on scraps without impacting the shark's well-being.
The remora benefits from the shark by hitching a ride, feeding on scraps of the shark's meals, and gaining protection from potential predators. The shark is not directly affected by the remora but may benefit indirectly by having the remora remove parasites from its skin.
Yes, the remora fish uses its sucker on top of its head to attach itself to the bottom of the shark thereby the shark is protecting the remora from predators.
