Answer 1

Explanation:

Mammals of the families Delphinidae (ocean dolphins), Iniidae, Lipotidae, Pontoporiidae, and Platanistidae (all river dolphins). Among the most well-known species are the bottle-nosed dolphin and the killer whale (a dolphin). The common name dolphin is applied to small cetaceans having a beaklike snout and a slender, streamlined body, whereas porpoises are small cetaceans with a blunt snout and rather stocky body.
