The Tangaant are highly protective of their habitat and will attack anything that enters it regardless of size. It is often referred to as "The Spitter" as it shoots out an adhesive/corrosive liquid from its tail. The first time a Tangaant appears before Jim Peyton is as a boss battle before retrieving mission critical equipment. Once the tail is destroyed, the Tangaant will almost constantly face Peyton to hide the weak spot, it is however still showing right between its back armor plates and can be shot with enough precision.
