Snorkeling in 2-5 feet of water.
This was disturbing. I found this half-fish floating face-down in the shallows right as I was about to exit the water. I grabbed it to take advantage of the opportunity for close-up photos, and it wriggled away! It was still very much alive-- pectoral fins swimming, eyes looking around, mouth opening sometimes. :(
Diving along the north side of Napili Bay, max depth 15 feet.
