Whales
Whales are large marine mammals descended from land-dwelling ancestors, including the blue whale, the largest animal known to have ever existed on Earth.
Descended from four-legged land animals that gradually returned to the ocean tens of millions of years ago, these marine giants include a species larger than any dinosaur that ever walked the Earth.
Descended From Land Animals
Whales evolved from land-dwelling mammal ancestors that gradually returned to an aquatic lifestyle over roughly 50 million years, retaining mammalian traits like live birth and nursing young.
The Blue Whale's Extraordinary Size
The blue whale, the largest whale species, is also the largest animal known to have ever existed on Earth, larger than any dinosaur, reaching lengths of up to 100 feet.
Complex Communication
Many whale species communicate through complex vocalizations, with humpback whale songs in particular recognized as remarkably sophisticated and structured, changing gradually over time within populations.
Recovery from Historic Whaling
Many whale populations were severely depleted by commercial whaling throughout the 19th and 20th centuries, though international protections have allowed some species populations to gradually recover in recent decades.
