Dolphins are examples of which animal group?

Explanation:
Dolphins are mammals because they share key traits that define that group: they are warm-blooded, breathe air using lungs, and nurse their young with milk produced by mammary glands. Even though they live in water, these characteristics set them apart from fish (which use gills and typically lay eggs or have different reproduction) and from reptiles or amphibians, which have different body coverings, respiration methods, and reproductive patterns. So dolphins belong to the mammals.
