General description: Sea serpents are one of the two surviving races of magic users in Hestuphia. And much like the second race, they are unknown to the mainlands. They are fully sapient creatures with a society and a town. They live deep underwater, usually around 11,000-12,000 kilometers. To compensate for the extreme pressure, they have a high bone and muscle density, making them highly durable creatures. A sea serpent looks close to a mix between a shark and an eastern dragon, with slender bodies and long tails that when looked at from the side gives them a slightly oblong shape. They are mostly androgynous, with the males having a slender build and the females having a small, but noticeable chest. A male sea serpent is often 6-6.5 feet (1.82-1.98 meters) long while the females can be anywhere from 7-8 feet (2.13-2.43 m) long, not including the tail which is commonly anywhere from one to one and a half times the length of the body. They have bioluminescent marks on their bodies that are often ring shaped, much like the spots on a snow leopards, and they can control the brightness of individual markings to communicate with each other.

Each sea serpent has two legs, and four sets of arms. The first set is prehensile and look not unlike a human arm. The secont set is more akin to the wings of a wyvern, but fins instead. These second arms have limited mobility and are attached by a hinge joint which allows only a 2-dimensional range of motion. Most sea serpents use these to control the speed of swimming, the further tucked into the sides they are, the faster they can go. While the limbs with the fins can only move in a 2-dimensional range, the fins themselves can rotate in order to increase drag to slow down swimming or allow for balance in a more upright stance. Aside from the arms, the main fin is found on the back. While each sea serpent has a wide array of magical capabilities, the society as a whole specializes in floramancy, and often their plant based spells are better than any other tool in their arsenal.

Gender Differences: During a hunt, the group divides itself into a male and female group, with each hunting pack having around half a dozen males and only one or two females. The males are known as the Snares while the females are known as the Flares. The males will sit and hide while the female goes and scares off prey with loud noises and bright lights. The Flares chase a prey into the area the Snares are waiting, allowing them to ambush with a trap or a surprise attack. As a result, the females have evolved to develop a larger, wider, and more intimidating build. As well as brighter colors and bioluminescence on the arms, stomachs, back, and legs. Their colors are often ones not commonly found in the oceans, such as bright yellows, oranges, or reds. And they have the ability to let their bioluminescence glow brighter for a short time, this is known as Flaring Up. The males, being the ambushers, commonly have more toned down colors or colors suited for camouflage, such as coral pinks, cyans, teals, and sandy or earthy tones. They have smaller frames, and only have glowing marks on their backs and stomachs.
