Is the humpback whale an odontocete?

No, the humpback whale is not an odontocete; it is a member of the baleen whale suborder, Mysticeti. Odontocetes, or toothed whales, include species like dolphins, sperm whales, and orcas, which have teeth instead of baleen plates. Humpback whales filter-feed using baleen to consume small fish and krill.
