Full Answer

The shark uses its forward momentum to keep swimming. A shark has the ability to change the angle of its fins to alter its direction through the water. A shark must swim constantly or else it sinks to the bottom. Unlike other fish, a shark does not have a swim bladder, an organ that provides buoyancy to other fish. Sharks can swim at great speed and turn quickly when needed.

    What type of relationship do remora and sharks have?

    A:

    Remora and sharks have a commensalism relationship which, according to the Encyclopedia Britannica, is a relationship between two species in which one benefits from the other without either being harmed. Commonly called a suckerfish, the remora is a pelagic marine fish that attaches to the shark and feeds on it. Unlike parasitic species, the remora does not penetrate the flesh of the shark or otherwise cause it damage.
