What are sea animals called?

Marine mammals are classified into four different taxonomic groups: cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea lions, and walruses), sirenians (manatees and dugongs), and marine fissipeds (polar bears and sea otters).

There are a lot of animals in the sea. Most are big but when you try to whale watch in your country, you only see few or from afar. I wonder where is the sea or ocean where you can have whale watching?

There are a lot and it depends on your location or until how far you can travel. Some places where you can watch are located in Baja California Sur, Mexico, North Cape Massachusetts U.S.A., we also have here in the Philippines at Oslob Cebu.
