About Cetaceans

Cetaceans are marine mammals with streamlined (hydrodynamic) bodies that glide easily through their watery environment, horizontal flukes, front flippers for steering and a layer of blubber directly under the skin.

According to the Society for Marine Mammalogy, 88 species of whales, dolphins, and porpoises are included in the Order Cetacea.

Students from the Museum’s Apprenticeship Program have developed fact sheets for their chosen marine mammal species.
