Question

The remora has a suction cup on the top of its head to attach to the shark. It eats the excess food that the shark doesn’t eat and also gets a free ride (using no energy of its own for movement). What does each organism get out of this relationship?

Answer 1

Answer:

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.

Explanation:

These fish attach themselves to the larger marine creatures including sharks, turtles, manta rays and the like for an easy mode of transportation, to gain the protection provided by being one with the bigger animal, and for food. Yet their hitching on to a shark causes no harm to the shark itself

Answer 2

The type of relationship between the shark and remora is Commensalism.

• Commensalism is a kind of relationship between organisms in which one organism gets benefits whereas the other organism has no use from such a relationship.
• In the case of the relationship between Remora fish and shark, the Remora would attach itself to a shark and use the shark for transportation and eat all the food that is left over from the shark. However, the shark gets no benefit.
• These remora fishes attach themselves to larger marine creatures like sharks, turtles, and manta rays and get an easy mode of transportation, to gain the protection provided by being one with the bigger animal, and for food. Yet being attached to a shark causes no harm to the shark itself.
