Rakk are medium-sized coatls, with flat, fleshy heads ending in a pointed snout. This snout is topped with a bony, armored plate along the head's dorsal region. They have a slit-like mouth along their ventral axis which is filled with hooked, rasping barbs. Like other coatls their only limbs have evolved into wings to keep them aloft, so Rakk have evolved a hooked talon at the end of their semi-flexible tail that allows them to cling to rocky surfaces. Similar to bats, they will rest upside-down.
They are resilient creatures, able to survive in slagged environments so long as they are slowly introduced to it, producing a variant called Slagged Rakk. Unlike their cousins, the Badass Rakk, they are unable to survive in other types of environments in such a way, though a subspecies known as Volcanic Rakk has arisen over time.
Rakk are naturally fragile creatures, and because of this they have developed a highly social structure that utilizes other subspecies in a tasked-based hierarchy that includes scouts, hive defenders, food processing, and it is believed to even include long-term storage in a manner similar to Honeypot Ants on Earth. Rakk communicate to one another through vocalizations that include a screech. This is often used to rally the flock against a particular threat or potential meal. When attacking, Rakk usually swoop in diving runs, using their wicked tail talon to lacerate their foe into submission. This also allows them to keep from slowing down, thus regaining altitude quickly for another run.
Rakk have developed a symbiotic relationship with an organism known as the Rakk Hive. The Rakk will crawl into the being's porous skin. This lets the Rakk Hive hibernate in relative peace while the Rakk themselves gain shelter and are protected from their own predators by the sheer size of their host.
