Description[edit]

Solaster stimpsoni is a large species, growing up to 50 cm in diameter. It can have 8 to 12 arms, but usually has 10.[2] 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.[5] They contain no pedicellariae. The underside of the arms have two rows of tube feet.

Distribution[edit]

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.[4]

Habitat[edit]

Solaster stimpsoni usually lives on rocky surfaces in the subtidal, and occasionally the low intertidal zones, at depths from 0 to 610 metres.

Diet[edit]

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[edit]

Solaster stimpsoni is eaten by Solaster dawsoni, the morning sunstar.[3]
