Visit an aquarium, planetarium, and natural history museum—all under one living roof.
Steinhart Aquarium is one of the most biodiverse and interactive aquariums in the world. Home to an estimated 40,000 animals, representing more than 900 separate species, it offers guests an unprecedented view of underwater life and provides insights into the critical role that aquatic environments play in life on Earth.
The original Steinhart Aquarium (which opened in Golden Gate Park in 1923) was the model for many of the public aquariums that followed—and today's Steinhart carries on that tradition. The aquarium's expeditions, research, and advances in animal husbandry result in a wide range of awe-inspiring exhibits, including the world’s deepest living coral reef tank, a four-level rainforest dome, the unique, ever-changing Water Planet gallery, and more.
Philippine Coral Reef
At 25 feet deep and holding 212,000 gallons of water, the Philippine Coral Reef tank is one of the deepest exhibits of live corals in the world. It houses a broad range of aquatic life from the coral reefs and mangroves of the Philippines, one of the most diverse reef ecosystems in the world.
Tusher African Hall
Live tortoises, lizards, and fish bring African Hall to life, but the undisputed stars of the show are the African penguins—a colony whose home is modeled after South Africa's Boulders Beach. Watch them preen, eat, and dive in the hall's 25,000-gallon tank.
Rainforests of the World
The Osher Rainforest is teeming with live animals, including free-flying tropical birds and butterflies and exotic reptiles and amphibians. Climb through three tiers of rainforest canopy and descend into our 100,000 gallon Flooded Forest tank, where freshwater fish cruise overhead.
See stunning views of the spectacular underwater ecosystems in our very own backyard, from kelp forests filled with leopard sharks to rocky reefs blanketed in vibrant pink anemones and colorful corals.
Walls that seem to flow into one another create an immersive, liquid setting that encourages exploration of the dramatic connections between water and life.
An ornate seahorse railing from the original Steinhart Aquarium surrounds the lush Swamp Gallery, where alligator snapping turtles and colorful koi circle the albino alligator known as Claude.
Explore some of the wildest courtship and mating strategies in the animal kingdom. From mate-munching bugs to leaping fish, learn how animals go to extremes to pass on their genes.
