The body length of these serpents is roughly 15 to 18 feet, with a girth of up to 3 feet. They are covered with rough-edged scales of brown, green, or blue coloration, giving their hides a mottled appearance. Their heads are short, with thick, muscular necks concealed beneath a webbed fringe.

Spitting sea serpents are a fiercely territorial, if not terribly intelligent, species that can be a great hazard on unfamiliar coasts. They are renowned for their great ability to spit globs of acidic spittle onto creatures that threaten them. The spitting sea serpent always tries to use its spitting attack against any that anger it, using its bite and constriction attacks against food or as a last resort.

A spitting sea serpent prefers to dwell in shallow coastal waters and coastlines, and avoids deep water where they are ill-equipped to handle encounters with large marine predators, against which their ability to spit is ineffective. They prefer to live in wild, uncivilized lands, and fiercely protect their hunting grounds from intrusion by any other predators.
