Sahuagin

Sahuagin are a fish-like monstrous humanoid species that live in oceans, seas, underground lakes, and underwater caves. Sahuagin speak Sahuagin. Some have been known to speak Common and Aquan.

Description
Sahuagin are usually green skinned, darker on the back and lighter on the belly. Many have dark stripes, bands, or spots, but these tend to fade with age. An adult male sahuagin stands roughly 6 feet (1.83 m) tall and weighs about 200 pounds (91 kg). Sahuagin are highly fish-like, with webbed feet and hands, gills, and a finned tail.

About one in every 216 hatchlings possesses four functional arms. While Sahuagin usually kill off defective hatchlings they allow these to live.

Society
Sahuagin are the natural enemies of aquatic elves and lizardfolk. Elves and sahuagin cannot co-exist peacefully: wars between them are prolonged, bloody affairs that sometimes interfere with shipping and maritime trade. Sahuagin tolerate the lizardfolk much more than they do the elves. Sahuagin have an only slightly less vehement hatred for tritons. Precisely why the two races hate each other so much is unknown, but what is known that the presence of an aquatic elf community within several miles of a sahuagin community occasionally causes some sahuagin to be born as malenti; mutants who resemble aquatic elves.

Savage fighters, sahuagin ask for and give no quarter. When swimming, a sahuagin tears with its feet, striking with its talons or a weapon. About half of any group of sahuagin are also armed with nets.

Religion
Sahuagin worship Sekolah, the lawful evil god of sharks, as their patron deity and the father of their race. They make regular, living sacrifices to Sekolah by feeding victims to the sharks that follow every sahuagin priest.
