Strongylocentrotus droebachiensis
From Natural History of Southeast Alaska
Green sea-urchin (Strongylocentrotus droebachiensis): This is the common species of harbors, calm bays, and tidal flats. Compared to Strongylocentrotus purpuratus, this species is pretty "wimpy," with slender spines and a more fragile look and feel overall.The real identification problem comes from White sea urchin (Strongylocentrotus pallidus), which is a subtidal species which tends to be paler and not as tall proportionately as this species. If you have a test or a particularly perplexing specimen, look closely at the pores: in this species they are arranged in sets of five pairs, as opposed to six or seven pairs in White sea urchin (Strongylocentrotus pallidus).
