One of the smallest of the Monoanticherans native to the island of Thalassia, the Zahnquirls are most famously known for their bizarre lower jaws. Not unlike a buzz saw in appearance, this component of the first head - when not utilized in sexual display - is used for slicing through the flesh of their prey with a saw-like motion, cutting off strips small enough for their secondary heads to consume. Said secondary heads also possess an unusual appearance; bearing a similar structure to that of the unrelated Fututoriformes, the presence of claw-like structures aid them in gripping small prey such as Trikes and Picozoans, which make up over 60% of their diets.
Zahnquirls are social hunters, forming organized groups, or more accurately harems, as they consist primarily of females with a sole male at the head. In order to take down larger prey such as the various Bounderjaws, they rely primarily on ambush tactics, with one member chasing the targeted prey towards it's pack mates. During the mating season, males will attempt to defend their mates by scaring off potential rivals by displaying their lower jaws prominently. While violence is often avoided as typically the ones with larger jaws win, it is not uncommon to find individuals with severely scarred hides.
