Does the pilot fish help the shark?

Asked by Dariel Lyons

Meet the Pilot fish, a little swimmer with some big friends. … In return for the protection, pilot fish keep the shark free of harmful parasites and clean up bits of excess food. In fact, such is the level of trust between the animals that pilot fish are even known to enter their shark’s mouth to nibble away food debris.
