No, a crab on a jellyfish would not be considered commensalism. Commensalism is a type of symbiotic relationship where one organism benefits without affecting the other organism. In this case, the crab is potentially benefiting by using the jellyfish for protection, while the presence of the crab may have negative effects on the jellyfish, making it more of a parasitic relationship.
