There was a fair variety of aquatic life, but because I am a poor photographer all I managed to get are these yellow fish.
Perhaps the most visually striking fish seen were the iridescent parrot fish. When one was near, you could HEAR it, due to it gnawing at the coral. Their grinding up the coral is how the white sand is made on the island's beaches.
Another amusing sight was a large "ALOHA" spelled out with rocks a few stories deep.
