I'd say a mutual relationship. The remora gets fed, transportation, and protection, while the shark gets parasites and other types of filth cleaned off of it. They both benefit in some way. Some could argue commensalism because the shark really doesn't benefit in a great way but I've seen many documentaries where sharks and other predatory animals allow small critters to clean them, even clean inside their mouth's. So they obviously care for hygiene which in fact benefits themselves.
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.
A Shark
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.
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.
Shark, remora
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.
The advantages of the remora and shark is that the remora hitches rides from the shark and eats the leftovers from the sharks meal.
the shark provides the remora with protection from predators and a food sorce ( i only know this because im a fish maniac)
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
A remora is a type of fish that has a special sucker on the top of it's body. It frequently attaches itself to large fish like sharks, and will feed on the scraps left over when the shark feeds. The remora does not harm the shark in any way, and the sharks do not feed on the remora.
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.
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.
