The Hawaiian green sea turtle, also known as Honu, is a large marine reptile found in the warm waters of the Hawaiian Islands. These turtles can weigh up to 400 pounds and have a distinctive heart-shaped shell that can reach up to 4 feet in length. They primarily feed on seagrass and algae, playing a crucial role in maintaining healthy marine ecosystems. Hawaiian green sea turtles are known for their long migrations, often traveling hundreds of miles between feeding and nesting sites. They are a protected species under the Endangered Species Act due to threats from habitat loss, pollution, and entanglement in fishing gear. Conservation efforts are in place to help ensure their survival.
