  ## Description
  
  Solaster stimpsoni is a large species, growing up to 50 cm in diameter. It can have 8 to 12 arms, but usually has 10. The aboral surface has a distinctive reddish orange colour and is covered with thick paxillae. The arms are long, slender, and tapering, each with a dark, purplish-grey contrasting stripe, running from the centre of the body to the tip. They contain no pedicellariae. The underside of the arms have two rows of tube feet.
  
  ## Distribution
  
  This species is found in the seas of Japan, and along the western coast of the United States, from central California, to as far north as Alaska.
  
  ## Habitat
  
  Solaster stimpsoni usually lives on rocky surfaces in the subtidal, and occasionally the low inter-tidal zones, at depths from 0 to 610 meters.
  
  ## Diet
  
  This starfish feeds on various small sea cucumbers, such as Cucumaria miniata, Cucumaria curata, Eupentacta quinquesemita, Eupentacta pseudoquinquesemita, and Psolus chitonoides. It also eats brachiopods, ascidians, or sea pens.
  
  ## Predators
  
  Solaster stimpsoni is eaten by a close relative, Solaster dawsoni, the morning sunstar.
