The Hawaiian monk seal (Monachus schauinslandi) is one of the most endangered marine mammals in the world and their population is declining. Monk seals are endemic to Hawaii, meaning they are native and are not found anywhere else in the world. Hawaiian monk seals are protected under the Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), and state law in Hawaii.
