About the coin: Bisa sea turtles are found in the tropical waters of the Atlantic, Pacific, and Indian Oceans. They are recognizable by their narrow, pointed beaks and distinctive, brightly colored shells. This species of turtle typically avoids deep waters, favoring coastlines and coral reefs. They are most commonly seen in the northern part of New Zealand’s North Island, in the shallow waters around the island.
