Descended from thrasher scylarians that made their way to the coast, bloodfin scylarians have spread into the neighboring Jujubee Ocean and have come to thrive in coastal and shallow waters. Equipped with a hardened plate that covers their heads, they are well equipped for hunting their prey. Their crimson eyes are adapted to seeing well in low-light waters, the perfect time to catch ones prey unaware. A small spine at the base of the head provides protection, when young, from larger predators such as a fully grown emperor seaswimmer.
Sticking close to coastal waters, bloodfin scylarians are adept scavengers, being able to pick up a scent trail from miles away and then follow it for days. When a feast is big enough, hundreds of them may come together to feed, and it is during these times that mating occurs. The resulting young will stick to the shallows for protection and will feed on the young of other species. They will reach maturity within several years, but until then they are vulnerable to most larger predators.
It is rare for one to encounter an individual that is not marred by hundreds of scars all over its body.
