What type of symbiotic relationship is a shark and a remora fish?
Mutalistic Relationship, both are benefiting. The shark is getting cleaned and groomed while the remora is getting fed and transported.
Plus,
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 What_is_the_symbiotic_relationship_between_remoras_and_a_shark. 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.
CHEESE!

When did megalodons get extinct?
Megalodon sharks then died after the medieval times. (but not 100% sure) One of the effects to this would be based on food and hunters who hunt them because of their babies they would have to try their best to protect them in every way possible. Some creatures who hunt megalodons babies are orcas (kiler whales) and great white sharks . More killer whales are beginning to hunt on the creatures that the Megalodons hunt! Therefore megalodonns have died out through time. Also you may think that megalodons could eat a great white whole or something but they can't because a great white was still "king of the seas and the most powerful of the seas" (no one could take him down even though a megalodon is about 2 times bigger)
^That guy is crazy, thinking that they died out after medival times when it died out millions of years ago. You seriously think a Megalodon can't swallow a great white whole when its THREE times bigger. I'm pretty sure that this guy has no idea about megalodons and that he shouldn't be answering your question before doing any research.

basking shark
Yes but if your talking about human attacks it's not that the shark wants to attack a human. It's a feeding instinct, when we're in the water we move like any creatures a shark preys on such as birds and smaller fish, they don't know it's a human in the water
