What is a neutral relationship with great white sharks?
Commensalism. A commensalistic relationship is one in which one organism benefits and the other organism is unaffected, meaning it is neither harmed nor benefitted. The classic example of commensalism is that of sharks and remoras. Remoras are scavenging fish that cruise around with sharks.

How many relationships do the great white sharks have?

What is the remora and shark relationship?
A Remora fish would attach itself to a shark and use the shark for transportation and eat all the food that is left over from the shark. The symbiosis relationship between them is a commensalism relationship because the remora is getting its food and the shark gets no benefit.
What do Remoras do for sharks?
The remora receives more than a convenient food source; the sharks protect them from predators and give them free transportation throughout the oceans. Remoras keep the waters clear of scraps around the shark, preventing the development of unhealthy organisms near the shark.
Why do sharks not eat remora fish?
In return, sharks do not eat pilot fish because pilot fish eat their parasites. This is called a “mutualist” relationship. Remoras are also known as suckerfish or shark-suckers as they are commonly found attached to the bottom of sharks hitching a ride across the oceans.
Do Remoras harm sharks?
If you’ve ever watched documentaries on sharks or have watched them out in the water, you’ve probably noticed their smaller companions, remora fish. Yet their hitching on to a shark causes no harm to the shark itself.
Why do little fish swim under sharks?
Pilot fish follow sharks because other animals which might eat them will not come near a shark. Small pilot fish are often seen swimming into the mouth of a shark to eat small pieces of food from the shark’s teeth. Sailors even said that sharks and pilot fish act like close friends.
What are the fish under sharks?

Are Remoras harmful?
Remoras are large, gray, parasitic fish usually found stuck to the sides of sharks, manta rays, and other large species. Remoras are not dangerous to their hosts. Remoras have been known to attach to a diver’s tank or body. As long as the diver is covered by a wetsuit, the remora does no harm.
Are Remoras good eating?
The taste (mild, no aftertaste) and texture (firm white meat) were both excellent. In appearance and taste, the remora was similar to triggerfish. The downside: The yield, per fish, was surprisingly small, so you have to catch big ones.
Do Remoras have predators?
Depending on the species, remora can travel attached to the body of sharks, rays, swordfishes, marlins, sea turtles or large marine mammals such as dugongs and whales. Remora eats leftovers of its host’s meals and collects parasites, bacteria and dead, epidermal tissue from the surface of the skin.
Where do sharks and remoras live?
The Remora is most often found offshore in the warmer parts of all oceans attached to sharks and other marine fishes and mammals (Unesco 1989).
What is a Sharks purpose?
As apex predators, sharks play an important role in the ecosystem by maintaining the species below them in the food chain and serving as an indicator for ocean health. They help remove the weak and the sick as well as keeping the balance with competitors helping to ensure species diversity.
