Ceanataur is a Carapaceon introduced in Monster Hunter 2. It is known to inhabit subtropical zones and can be encountered at all ranks.
Similar in appearance to the Hermitaur with sharper claws, leg stubs and a higher-edge shell. The shell on its back was actually grown by the Ceanataur itself. Only when it grows much larger into a Shogun Ceanataur will it replace its shell with a larger monsters skull, like a Gravios skull.
It is able to spit a small ball of poisonous fluid at foes. Sometimes, a Ceanataur may wait beneath the ground for prey or a hunter to pass, jumping out of the ground and striking them when they walk over. A Ceanataur that's burrowed underground can be spotted by the puffs of dust that it regularly spits out.
Ceanataurur lives mainly in Volcano, where its extremely sharp claws allow it to tunnel through the dense rock.
