A mermaid is an aquatic creature with the head and torso of human female and the tail of a fish. The male version of a mermaid is called a merman; the gender-neutral plural is merfolk.They were known to sing sailors to their deaths or squeeze the life out of drowning men, while trying to rescue them.

A mermaid has eyes of a fine light blue; its nose small and handsome; its mouth small ,lips thin and its teeth small, regular, and white.Its chin well shaped, its neck full, its ears like those of the eel, but placed like those of the human species; and behind them are the gills for respiration, which appear like curls.

Merfolk are about 8 feet long from the top of the head to the end of the tail, and weigh about 400 pounds.

Most merfolk encountered outside their home are warriors; the information in the statistics block is for one of 1st level.
