Mottled Star
Mottled Star, sometimes called Troschel's Sea Star or Evasterias troschelii to it's friends. This particular one was hiding on the underside of a Lewis's Moonsnail egg collar - sand, eggs and mucus. This star is also a shellfish eater - the white spots on the arm tips are apparently a primitive eye.
Leather Star
Leather Star or Dermasterias imbricata to it's friends. Apparently it eats sea anemone's and sea cucumbers (unlike the Ochre Sea Star that his here to feed on shell fish)
