Additional Creatures Wiki

Brachauchenius is a reptile in Additional Creatures.


Brachauchenius is one of the ocean’s apex predators. Rivaling Prognathodon, Mosasaurus, Tusoteuthis and Purussaurus, Brachauchenius is a gigantic relative of the much smaller Liopleurodon. Most other apexes of the ocean seem to focus on sheer power. While Brachauchenius is indeed a powerful animal, it seems to have traded some strength and durability for agility. Brachauchenius uses its four long, strong flippers for surprising maneuverability and agility- lacking a drastic turning radius like many other large animals: its even capable of turning in place if needed! With knife-like teeth that shred and cause bleeding, this powerful ocean predator is a versatile must-have for any survivor’s oceanic arsenal.

The Brachauchenius can turn in place.

The Brachauchenius is immune to electrocution and resistant to electric-type attacks.

The Brachauchenius has a "hunger" mechanic, where once it has feasted on a corpse it will become neutral towards players and creatures. This pacified state is indicated by a green aura around its head, which is when it is susceptible to passive taming.

While capable of being tamed using both common methods, Brachauchenius tames 5x more effectively with passive taming.


  • Brachauchenius means "Short Neck".
  • Brachauchenius is only one of three bearers of the hunger mechanic, along with Metriacanthosaurus and the Tiger Shark.
  • In ARK, Brachauchenius is one of the ocean's largest predators, being on par with Mosasaurus, and Tusoteuthis. Its only true fear is Purussaurus.
  • Brachauchenius is one of the last pliosaurs known to exist before the group became extinct during an ambiguous extinction event 90 million years ago. It's unknown what caused this extinction event, but it's believed to be the cause of the extinctions of various other groups such as ichthyosaurs, allosauroid theropods, and spinosaurs.
  • The Brachauchenius's design is inspired by the Liopleurodon from Walking with Dinosaurs.
  • Brachauchenius is planned to be removed in the future.
