One of my favorite animals, the magnificent but sadly endangered, green sea turtle (Chelonia mydas), also known as the green turtle, black (sea) turtle, or Pacific green turtle. There are two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name comes from the usually green fat found beneath its carapace; these turtles' shells are olive to black.
The great or giant barracuda (Sphyraena barracuda) is a ray-finned fish known for its large size, fearsome appearance and ferocious behaviour. It is so impressive to be surrounded by a school of them. Shot while diving in Indonesia.
