COVER A blood star (Henricia leviuscula) near Whidbey Island, Washington state. It is one of 10 species of sea star that appear to be affected by a mysterious wasting syndrome on the west and east coasts of North America. Various levels of mortality have been confirmed in 10 other species, making this the largest documented die-off of echinoderms. See page 464 and http://scim.ag/slide_6183.
