Polisan

Polisans are an aquatic species native to the planet of Polis IV, believed to have been a result of genetic experiments between Calatians and Chondrichites.
== Biology ==
Sharing many biological traits with Calatians and other subspecies, Polisans are characterized by their greyscale skintones, brightly colored hair and eyes, and skin markings similiar to Aludrans. While they possess four arms and pectoral muscles similar to Calatians, their fingers have retractable webbing that increases their swimming ability. Likewise, their legs from the waist down are scaled and digitigrade, ending in Aludran-like prehensile digits, again with retractable webbing. These scales extend to their tails, which while not as prehensile as other members of the Calatian genus, are considerably stronger and larger. While they are also capable of sporting stingers or mouths as common within the genus, they are also studded with a variable array of fins, varying between rigid and shark-like, to flexible ray-fins, to elaborate betta-like fins. These fins can also be found on their back, forearms, and legs. Like Chondrichites, however, Polisans possess functional gills in addition to lungs, albeit located beneath their arms as opposed to the neck. In addition, drawing from the abilities of both species, Polisans are able to fuse their legs and enlarge their tail in order to transform into a "mermaid"-like form. Drawing from Arkabids, Polisans are also able to alter not only their pigmentation for camouflage, but also their texture similar to an octopus or cuttlefish. While Polisans only have two eyes, they possess glowing dual-irises similar to Aludrans with white sclera. In addition, they possess nictitating membranes that cover their eyes when underwater. Sprouting from their head is a single horn they often use as a spear. Their ears, sporting fins, are much more capable than the ears of other members of the genus and permit the use of echolocation. This, paired with their specialized vocal cords, allow them to speak and hear without difficulty while underwater. Similar to Calatians, the Polis population is split roughly evenly between Males, Females, and Hermaphrodites.
