Marine mammals are aquatic mammals that rely on the ocean and other marine ecosystems for their existence. They include animals such as seals, whales, manatees, sea otters and polar bears. They are an informal group, unified only by their reliance on marine environments for feeding and survival.
The Steller sea lion, also known as the Steller's sea lion and northern sea lion, is a near-threatened species of sea lion in the northern Pacific. It is the sole member of the genus Eumetopias and the largest of the eared seals (Otariidae). Among pinnipeds, it is inferior in size only to the walrus and the two species of elephant seals. The species is named for the naturalist Georg Wilhelm Steller, who first described them in 1741. The Steller sea lion has attracted considerable attention in recent decades, owing to significant and largely unexplained declines in their numbers over an extensive portion of their northern range in Alaska.
Steller's sea cow is an extinct sirenian described by Georg Wilhelm Steller in 1741. At that time, it was found only around the Commander Islands in the Bering Sea between Alaska and Russia; its range extended across the North Pacific during the Pleistocene epoch, and likely contracted to such an extreme degree due to the glacial cycle. It is possible indigenous populations interacted with the animal before Europeans. Steller first encountered it on Vitus Bering's Great Northern Expedition when the crew became shipwrecked on Bering Island. Much of what is known about its behavior comes from Steller's observations on the island, documented in his posthumous publication On the Beasts of the Sea. Within 27 years of its discovery by Europeans, the slow-moving and easily-caught mammal was hunted into extinction for its meat, fat, and hide.
Monterey Bay Aquarium is a nonprofit public aquarium in Monterey, California. Known for its regional focus on the marine habitats of Monterey Bay, it was the first to exhibit a living kelp forest when it opened in October 1984. Its biologists have pioneered the animal husbandry of jellyfish and it was the first to successfully care for and display a great white shark. The organization's research and conservation efforts also focus on sea otters, various birds, and tunas. Seafood Watch, a sustainable seafood advisory list published by the aquarium beginning in 1999, has influenced the discussion surrounding sustainable seafood.

The Marine Mammal Protection Act (MMPA) was the first act of the United States Congress to call specifically for an ecosystem approach to wildlife management.
The Great Lakes Aquarium opened in 2000 and is located on the Duluth waterfront. A 501(c)(3) private nonprofit, Great Lakes Aquarium features animals and habitats found within the Great Lakes basin and other freshwater ecosystems such as the Amazon River. The Aquarium houses 205 different species of fish, birds, reptiles, amphibians and mammals. It is one of few aquariums in the United States that focuses predominantly on freshwater exhibits.
The Marine Mammal Center (TMMC) is a private, non-profit U.S. organization that was established in 1975 for the purpose of rescuing, rehabilitating and releasing marine mammals who are injured, ill or abandoned. It was founded in Sausalito, California, by Lloyd Smalley, Pat Arrigoni and Paul Maxwell. Since 1975, TMMC has rescued over 23,000 marine mammals. It also serves as a center for environmental research and education regarding marine mammals, namely cetaceans, pinnipeds, otters and sirenians. Marine mammal abandonment refers to maternal separation; pups that have been separated from their mother before weaning. At the center, they receive specialized veterinary care: they are diagnosed, treated, rehabilitated and ideally, released back into the wild. Animals in need of assistance are usually identified by a member of the public who has contacted the center. These animals represent the following major species: California sea lions, northern elephant seals, Pacific harbor seals, northern fur seals and southern sea otters. On a few occasions, TMMC has taken in Guadalupe fur seals, Steller sea lions and bottlenose/Pacific white-sided dolphins. The only non-mammals that TMMC takes in are sea turtles.
Mystic Aquarium is a marine aquarium in Mystic, Connecticut. It is one of only two U.S. facilities holding Steller sea lions, and it has the only beluga whales in New England.

It is a subsidiary of the Sea Research Foundation, Inc.
Aquarium du Québec is a public aquarium located in the former city of Sainte-Foy in Quebec City, Quebec, Canada.

It is operated by Société des établissements de plein air du Québec (Sépaq), and is a member of the Canadian Association of Zoos and Aquariums (CAZA).
A public aquarium is the aquatic counterpart of a zoo, which houses living aquatic animal and plant specimens for public viewing. Most public aquariums feature tanks larger than those kept by home aquarists, as well as smaller tanks. Since the first public aquariums were built in the mid-19th century, they have become popular and their numbers have increased. Most modern accredited aquariums stress conservation issues and educating the public.
Ocean Conservancy is a nonprofit environmental advocacy group based in Washington, D.C., United States. The organization helps formulate ocean policy at the federal and state government levels based on peer reviewed science.
The Virginia Aquarium & Marine Science Center, formerly known as the Virginia Marine Science Museum, is an aquarium and marine science museum located in Virginia Beach, Virginia, just south of Rudee Inlet. The exhibits at the museum are contained in over 800,000 US gallons (3,028,000 l) of fresh and saltwater displays.
Sea otter conservation began in the early 20th century, when the sea otter was nearly extinct due to large-scale commercial hunting. The sea otter was once abundant in a wide arc across the North Pacific ocean, from northern Japan to Alaska to Mexico. By 1911, hunting for the animal's luxurious fur had reduced the sea otter population to fewer than 2000 individuals in the most remote and inaccessible parts of its range. The IUCN lists the sea otter as an endangered species. Threats to sea otters include oil spills, and a major spill can rapidly kill thousands of the animals.

All three aquariums feature dive shows, live animal encounters, and feeding programs.
Randall William Davis is an educator and researcher who studies the physiology and behavioral ecology of marine mammals and other aquatic vertebrates. His physiological research focuses on adaptations of marine mammals for deep, prolonged diving. Davis has continually emphasized the importance of studying aquatic animals in their natural environment and has spent many years developing animal-borne instruments that record video and monitor three-dimensional movements, swimming performance and environmental variables to better understand their behavior and ecology. His academic endeavors and 94 research expeditions have taken him to 64 countries and territories on seven continents and all of the world's oceans.
