Seen swimming near the dock at the lodge which is located in Batteaux Bay.
Common Name: Green sea Turtle
I'm assuming this is the right species as it's the one commonly seen round beaches in Hawaii.
The green sea turtle (Chelonia mydas), also known as the green turtle, black (sea) turtle, or Pacific green turtle, is a large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans. The common name comes from the usually green fat found beneath its carapace.
