The three types of symbiotic relationships are commensalism, mutualism, and parasitism.
Commensalism: One organism benefits from the symbiotic relationship while the other remains unaffected. Example: Barnacles and whales.

Parasitism: One organism in the symbiotic relationship benefits at the other organism's expense. Example: Fleas and dogs.
