A nycar is about 2-1/2 feet long with two diminutive legs that it uses to pull its serpentine body along with deceptive speed. Nycars are jealous creatures and usually hunt alone, although a mated pair may stay together until the female lays her eggs. Nycar eggs are black and about the size of an adult human's fist; a female will feed and look after hatchlings for up to a year, so long as they remain in her territory. Upon reaching adulthood, a nycar weighs about 12 pounds, and can live up to 90 years.
