Yurian

Colloquially known as crabmen, yurians are a humanoid race of crab-people that typically dwell in coastal caves and live as primitive hunter-gatherers. They continue to grow (and molt) throughout their short lives, with some reaching 10 feet or taller, though typical adults are 6-7 feet tall. They craft simple, impermanent artifacts, often possessed of a certain beauty, including seaweed weavings, driftwood carvings, and seashell constructions. Yurians rarely associate with outsiders, even other tribes of crabmen.
