Body often yellow or green, arms pale, sometimes with a long purple stripe along the top of the arms, and banded near the arm tips. Disc puffy with minute spines over the surface. Paired plates on the disc near the arm bases (radial shields) are sunken. Arms with many spines (>10) along the sides of each segment. Arms long. Disc up to 2 cm wide, arm up to 15 cm long.
This animal is typically found with disc buried in the seafloor and 2-4 arms poking out of holes into the current. It feeds by extending its mucus covered tube feet perpendicular to the arm; these extended tube feet are much longer than the arm spines and can catch plankton as it passes by.
In soft sediment, including sandy channel banks with strong tidal movement, to depths of 300 m.
