Step-by-step explanation:

Mammals are a type of animal which are classified through several factors.

• these vertebrates posses
• hair or fur
• three bones in the middle ear
• a brain region for higher-order brain function, the neocortex
• nurse their young with milk from mammary glands

Whales are fully aquatic mammals, with specialized adaptations to thrive in their environment. These adaptations, like blubber, allow these mammals to maintain their body temperatures in cold environments. They are part of the order that includes their closest relatives as even-toed, hoofed land dwelling mammals called Cetartiodactyla, as a suborder, Cetaceans. Balaenoptera is a genus of whales with around eight distinct species, including the fin whale and minke whale.
