Do Seals and Whales Live Only in the Atlantic? No—They're Global

The premise is incorrect. Seals (pinnipeds) and whales (cetaceans) inhabit all major oceans:

• Atlantic: Humpbacks, right whales, harbor/gray seals.
• Pacific: Gray whales, orcas, elephant seals, Steller sea lions.
• Indian Ocean: Blue whales, dugongs, various dolphins.
• Southern (Antarctic): Minke whales, leopard/crabeater/Weddell seals.
• Arctic: Bowhead whales, narwhals, belugas, ringed/bearded seals.

Many species are cosmopolitan (e.g., orcas, humpbacks, blue whales). Distribution depends on food, temperature, breeding grounds, and evolutionary history—not ocean boundaries.
