Presiding almost solely within the island's swamps, Diplocaulus Natatorinutrix is a small amphibian that primarily eats minor fish. It rounds out what I consider the middle-bottom of the ecosystem, feeding on the tinier non-insect creatures of the island while itself being a common snack for the larger carnivores.

Because so many creatures prey on it, Diplocaulus has become very skittish and often flees at the first sign of trouble. It uses its amphibious nature to escape into whichever environment its predator isn't native to. Diplocaulus' unique capability to retain vast quantities of oxygen allows it to effectively remain submerged for hours at a time, usually outlasting even other amphibious creatures that might otherwise prey upon it.


There are only a few uses for tamed Diplocaulus. It is primarily used for the (rather disgusting) practice of employing Diplocaulus as an oxygen bag. Diplocaulus stores air in the bladders of its head, and divers can suck from these bladders to take deep breaths while submerged, supporting long-term underwater exploration without the use of external gear.

— The Dossier

The Diplocaulus is a small carnivorous (piscivorous) amphibian found on the Ark.

Wikipedia has a more detailed and comprehensive article on Diplocaulus





The Diplocaulus resembles a large newt with a low-slung and flabby body, slimy skin, and a paddle-like tail for moving through stagnant swamp water. However, the creature's head makes it impossible to mistake for any other creature. Shaped like a boomerang, the amphibian's head has two primary purposes. First, like a hydrofoil, its vanes improve its swimming speed to escape any predator. Second, it has evolved to store air bladders, a trait unseen in its fossil kin. These bladders act as buoyancy manipulators, allowing it to dive deeper by expelling air or move to the surface by filling them up.

Color Scheme and Regions








  • The dossier was revealed on October 2, 2015.
  • The dossier suggests the ability to breathe from it, allowing long diving trips for lower level players, to reach those precious oil rocks and silica pearls at the bottom of the sea.
