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, housing a broad range of marine life from the coral reefs and mangroves of this diverse archipelago.
Steinhart Aquarium is one of the most biologically diverse and interactive aquariums in the world. Home to nearly 40,000 animals, and 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.
