Hooktalon Dragons are a two-headed breed named for the long, curved claw that grows on the first finger of each of their hands. Their skin is tough and covered in razor sharp, tooth-like scales, and as they age they grow a dense, keratinous club on the end of their tail. Wild Hooktalons live in migratory, matriarchal clans around deserts and hot scrublands, hunting and stealing kills from other dragons as they please. They are notoriously ill-tempered and the females, being the largest and most aggressive of their kind, will often lash out at their male counterparts in brief, explosive disputes over anything and everything. The only creature with which a Hooktalon will not fight is itself: though the dragon has two heads and thus two brains, a strong connection between its brains allows them to function as one.
Two-headed dragons are unique enough to deserve a separate classification from ordinary dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, snapping back and forth. Their unique anatomy prevents them from breeding with single-headed dragons.
