Detailed explanation-1: -Symbiosis is when two organisms live together, but neither organism is beneficial. A marine example of commensalism would be a Whale Shark and a Remora, the Remora stays under the shark’s belly and catches and excess food that the shark has left behind.

Detailed explanation-2: -The most classic example of commensalism on reefs is the remora. Commonly called “suckerfish” or “sharksuckers”, these fish (of the family Echeneidae) attach themselves to the skin of larger marine animals like sharks and manta rays via a specialized organ on what we might consider their back.

Detailed explanation-3: -The relationship between remora fish and shark can be considered as mutualism. Remora attaches itself to the shark, to travel different parts of the sea by floating with the shark. It helps the remora fish to travel without burning energy. They also get to eat scraps of food dropped by the shark.

Detailed explanation-4: -The symbiotic relationship between remoras and sharks is mutualism because the two species benefit from the existence of each other. We’ve already seen that, like the pilot fish, remoras eat scraps of food and get protection from being with the host shark.
