Flatbottom Sea Star, Asterias amurensis

[Flatbottom Sea
Star, Asterias amurensis, staraster.jpg=60KB]

The flatbottom sea star, Asterias amurensis, in Alaska, is very abundant north and occurs locally south of the Alaska Peninsula; and it ranges from British Columbia, Canada (below 200m) to Japan (Lambert 1945). Its diameter is to 16 inches. Juvenile red king crab shelter themselves in between the arms of A. amurensis and E. troschelii, presumably for protection against predators or to feed upon food associated with these commensal hosts (Powell and Nickerson, 1965; Dew, 1990).

Scientific name: Greek asterias (starred).
