Turtapede

The turtapede, a docile, slow-moving Pandoran reptile, can be found lazily swimming through freshwater lakes and rivers, but has also adapted to saltwater oceans. Turtapedes have armored bodies and multiple fins. The dorsal fin increases in size with age, with the armored plates surrounding it falling off and regrowing to fit the increasing appendage. A fully grown turtapede is approximately 16 to 20 ft (5 to 6 m) from snout to tail and 13 ft (4 m) tall. Since the turtapede grow to incredible sizes, some larger shells can be used for rafts with the bones of the flippers fashioned into oars or paddles.
