Traits

Spino fins are a less frequently observed fin type across Aerius, and are characterized by four long spines and three large pieces of webbing whose edges are shaped like a ‘v’ that points in towards the body.  It is believed that long ago, this fin shape proved useful for communication among Abyssal dwellers, due to the large expanses of glowing fin, and that this is why it is only found in Abyssal bloodlines.  This fin type is generally more opaque.
