Marine life inhabiting the waters of Hawaii Volcanoes National Park is abundant and varied. Species include a variety of fish, such as surgeonfish, butterflyfish, parrotfish, wrasse, jacks, triggerfish and goatfishes; crustaceans like shrimps and lobsters; mollusks like octopus and squid; sea stars; coral reefs that provide homes for many species; sea turtles including the endangered hawksbill turtle; humpback whales which migrate through Hawaiian waters seasonally. There are numerous small invertebrates living in the park’s coral reefs that are often overlooked but important to its overall ecosystem.
