Question: are orcas dolphins or porpoises?
Answer: Orcas are classified in the Delphinidae family of dolphins and porpoises. All delphinids belong to the Cetacean order within the toothed whale (Odontoceti) suborder. This means that all dolphins technically are whales; however, the term "whale" is usually reserved for baleen whales of the Mysticeti suborder.
