Whales are whales.

Porpoises are porpoises.

Fish are fish. Sharks are fish. Whale sharks are fish.

Dolphins are dolphins.

Killer whales are whales.

Answer 2

No, whales are not dolphins but they are both mammals, and similar. They are both from the same family, but just like a pet cat and tiger are from the same family, and are both mammals they also have distinct differences, it is the same with whales and dolphins.

Both dolphins and whales belong to same order of aquatic mammals, known as Cetaceans. Many people (perhaps stubbornly so) refuse to call dolphins and porpoises "whales" even though they are whales in every way anatomically except perhaps in size. In pop-culture it is often assumed the only true "whales" are baleen whales (like the blue, humpback, or grey whales) with the exception of a few toothed whales (the sperm whale, beluga, and narwhal). This excludes animals classified as porpoises and dolphins (like the bottlenose dolphin, killer whale, and pilot whale).

Another Answer:

Since dolphins are part of the Cetacea Order (of scientific classification), technically all dolphins are whales.

Kingdom: Animalia

Phylum: Chordata

Class: Mammalia

Subclass: Eutheria

Order: Cetacea

The term whale sometimes refers to all cetaceans, but more often it excludes dolphins and porpoises, which belong to suborder Odontoceti (toothed whales). This suborder also includes the sperm whale, killer whale, pilot whale, and beluga whale.

Answer 3
