Describe two symbiotic relationships between reef dwellers other than the zooxanthellae-coral polyp relationship
What will be an ideal response?
Cleaner wrasses are fishes that occupy certain areas on reefs where other fishes come to get cleaned. The wrasses remove dead flesh and parasites from the customers, and in return the wrasses get a free meal. Another relationship is that of the anemone fish and anemones of coral reefs. The anemone fish lives within the tentacles of the anemone host and helps rid the host of debris and might supply the anemone with waste products that fuel the photosynthesis of the zooxanthellae within the anemone. In return, the anemone fish is protected by the stinging cells of the anemone from predators. The anemone fish may also lay its eggs beneath the anemone for added protection.
