Aquatic ecosystems are challenging for humans to explore. Most of our observations of aquatic life are superficial, being made from the water's edge or surface. Aquariums reveal the underwater world, a world that covers 80 percent of the Earth's surface and is usually hidden from our view. By discovering and understanding something about aquatic life, aquarium visitors become aware of the value of aquatic life and the need to protect and preserve it. Aquariums perform a vital role educating people about aquatic conservation.
The Vancouver Aquarium Marine Science Centre also takes direct action in conservation. Aquarium staff and volunteers have been involved in the creation of Canada's first no-take Marine Protected Area, beach clean-ups, wetlands restorations and rehabilitations, aquatic bird and intertidal population surveys and much more.

The Aquarium's mission also includes the research of aquatic life. One current research project involves learning why Steller sea lions are disappearing from many of their natural habitats. Aquarium researchers and scientists are also actively studying other marine mammals at the Aquarium and in the field, including killer whales, belugas, sea otters and harbour seals. Other researchers are revealing the unknown early life stages of the wolf-eel as well as sculpins, lingcod, blennies, shrimp, snailfish and other local fish species.
