Unlike the classical dragon, these great, scaly, serpentine beasts are generally agreed to be a product of evolution though many suspect magical influence, either deliberate or natural, somewhere in their evolution. \n'b' Whatever their origins, sea serpents are a highly-varied species, with great variation in  size , coloration, intellect, and temperament. However, all sea serpents bear certain similarities. They are long, sinuous, warm-blooded creatures that closely resemble snakes in appearance, though they all have two sets of flippers, which may be large or so small and atrophied as to be nearly unnoticeable. Sea serpents are aquatic creatures, though some can make their way about on land. All sea serpents can breathe both water and air with equal efficiency, another fact that distinguishes them from marine mammals and reptiles. Further, all sea serpents are sentient, with an intellect ranging from little greater than moronic to supragenius level. \n'b' One trait that sea serpents share in common with their draconic brethren is a sense of innate superiority, a feeling that they are masters of the sea, at least in whatever manner they choose to pursue their expertise. \n'b' Unlike dragons, however, sea serpents are not distinguished by color or age category. And while some species are as acquisitive as dragons, others have no interest in hoarding wealth and live lives little better than beasts. \n'b' All sea serpents can speak and understand Aquatic, and many know Draconic as well. The more intelligent species may also learn the languages of marine civilizations or the languages of sea-traveling surface-dwellers. \n'b' Due to their physical similarities, sea serpents use fairly consistent tactics in combat situations. All sea serpents have venomous bites, and they use this to their advantage to  slow  or immobilize multiple attackers so they can concentrate on one foe. In addition to their lethal bite, all sea serpents have the ability to ensnare prey in their coils as a giant constrictor does and crush the life out of them. The larger sea serpents may even use this constriction  attack  against sea vessels, and mariners in their smoky dens delight in recounting tales of horror and woe of great serpents that splinter hulls and then devour the helpless sailors in the water. \n'b' Because they are sentient beings, sea serpents can often be reasoned with even if the reasoning is no more complex than simple intimidation.\xc2\xa0They are adaptable to circumstances, and none throw themselves into battle rashly.\xc2\xa0This serpentine creature is about 20 feet long, nose to tail, with two sets of large flippers and a wide body. A finned crest runs the length of its back, head to tail. The body is dark blue with a lighter underbelly, often tinged with rust or green highlights.\xc2\xa0The brine sea serpent is a relatively stupid and aggressive predator of the deeps and is the only sea serpent with a breath weapon.\xc2\xa0The brine sea serpent lives in caves in the ocean floor, where it maintains a hoard much like a dragon. It often lives in seas known for their stormy conditions, since it enjoys feeding on humans capsized from boats.\xc2\xa0Sometimes it even attacks ships directly if it is hungry. It also searches sunken ships for objects of interest to add to its hoard. The eyes of a brine serpent are small, but it possesses large ears and has exceptional hearing. \n'b' Against lone prey, the brine sea serpent likely closes and  attack  with its bite. \n'b' When confronting larger groups, it uses its breath weapon first \xe2\x80\x93 the brine sea serpent has a special organ that harvests sodium from seawater and stores it in concentrated form in a gland in its cheek. It generally avoids constricting attacks unless attacking large opponents that do not die from its poisonous bite. The brine sea serpent may also use the constriction  attack  against small sea vessels if it is very hungry.'
