It's another Hyca Shark. There's gonna be a few of them, some I might sell as adopts. In the meantime I'm hoarding a whole ass fantasy giant aquarium.
These are the lines and base I made and may, or may not, alter it in the future.

Hyca Sharks
(Hick-uh)

Hyca Sharks are venomous and if threatened the small armored spines can secrete neurotoxins that cause whomever or whatever to go numb and lose control of their body temporarily. They're a small but long breed. Much like a thresher shark, a hyca shark can use its tail as weapon. Their pectoral fins are shaped differently than a typical shark, as they maintained their ancient shape, allowing for more diverse movement. In exchange however their pelvic fins are less obvious because of it.

Fun Facts 1:
Hyca sharks are found in a wide variety of colors and patterns. Their under sides tend to be lighter in color, much like their larger shark cousins. Their eyes have wide pupils, to help them see in the ocean and murky rivers. They also have sensor pits around their nose that aren't visible, but found on their skulls above their teeth, helping them find prey and avoid predators.
