Out of an abundance of caution during the COVID-19 pandemic, the touch pool section of the Edge of the Reef Exhibit is currently closed.

The Edge of the Reef Exhibit is a 7,500-gallon (28,400 liter) outdoor exhibit that recreates a profile of habitats you might find along a Hawaiian rocky shoreline. It is the longest continuously running exhibit at the Aquarium. The animals in this exhibit are typical fishes and invertebrates you might see snorkeling along Hawaii’s reefs, and include yellow tangs, parrotfish, butterflyfishes, rice coral, sea cucumbers, and bright red pencil urchins. This exhibit also incorporates an interactive area where Aquarium interpretive volunteers provide an up close and hands-on experience with some of the animals found in local tide pools.
