Tetsucabra prey upon anything smaller than themselves that ventures too close to the water. This includes Kelbi, Aptonoth, Jaggi, Rhenoplos and Slagtoth. Due to their large size and tough armor, they have only other large predators to be wary of. These include Gore Magala, Deviljho, Glavenus, Najarala, Stygian Zinogre and Kushala Daora. They compete for territory with other aquatic inhabitants, such as Zamtrios and Tidal Najarala in the Frozen Seaway.
Drilltusk Tetsucabra have many of the same adaptions as Tetsucabra, however, there is a few differences between them. Drilltusk Tetsucabra have abnormally developed jaws, yellow eyes, and darker colored scales. Their secondary name, Drilltusk, comes from their ability to pierce through the soil and even steel with their mouth. Drilltusk Tetsucabra jaws are strong enough to pick up rocks like light feathers. Unlike Tetsucabra, these individuals have both one shorter tusk and one longer tusk. From one tusk being slightly shorter, they are known to use them in some unsuspecting ways. The longer tusk is a good tool for piercing the earth. Not only can these Tetsucabra crush boulders with their jaws, they can even use their own weight to break apart the earth.
Drilltusk Tetsucabra is an aggressive Evil Faced Star. From its overwhelming strength compared to a normal Tetsucabra, Drilltusk Tetsucabra require a special permit to hunt.
