This green sea urchin (Strongylocentrotus droebachiensis) found near Victoria, is a herbivore and eats a wide variety of algae. It’s interesting how the tube feet of this urchin cover almost all of its surface area. The green sea urchin can grow to 3.6 inches (9 cm) across, with a range that is circumpolar and includes Japan, as well as northern Alaska to northern Washington.
