I WONDER - How Are Whales Grouped?

Marine mammals like whales, dolphins, and seals are well-known ocean creatures. They share traits with land mammals, such as being warm-blooded, breathing air, and nursing their young. Whales, the largest animals on Earth, are divided into toothed and baleen categories.
