Whale, any of the larger species of aquatic mammals belonging to the order Cetacea. Whales are the heaviest known animals, living or fossil, reaching a maximum size in the blue whale of perhaps more than 30 meters and 200 metric tons. They are distributed throughout the world’s oceans and seas.
Whales roam throughout all of the world's oceans, communicating with complex and mysterious sounds.

The whales are part of the largely terrestrial mammalian clade Laurasiatheria. The immediate clade is Cetacea, but if the dolphins and porpoises are excluded, the whales are paraphyletic. [12] If on the other hand the dolphins and porpoises are accepted as whales, then the sensu lato group is a clade, the Cetacea. [13] The phylogenetic tree shows the relationships of whales and other mammals ...
Whales are massive marine mammals that migrate thousands of miles, communicate with songs, and live for over a century.
Whales are the largest animals on Earth and they live in every ocean. The massive mammals range from the 600-pound dwarf sperm whale to the colossal blue whale, which can weigh more than 200 tons ...
