A nontoxic dye highlights water currents surrounding sea urchins (Astropyga sp.) off Vancouver Island, British Columbia. These small, spiny echinoderms are found in oceans all over the world.
A sea urchin�s vivid purple spines appear ready for action in this close-up view from God�s Pocket Marine Provincial Park, British Columbia.
The spines of the omnivorous pencil-spined urchin (Eucidaris thouarsii) extend outward from its body. There are some 700 species of sea urchins worldwide.
The spines of a fire urchin (Asthenosoma varium) form a multicolored flower off K
omodo Island, Indonesia. The blue swellings on the tip of each spine are filled with venom.
Found in the western Pacific, this sea urchin's blue-green spines branch out like tendrils from a plant. The long, movable spines protect the urchin from predators.
A striped urchin crab (Zebrida adamsii) finds its place on a red sea urchin (Astropyga radiata) in the western Pacific.
Sea urchins nestled in a Pacific kelp bed off California offer a sharp contrast in shapes between kelp tendrils and urchin spines. The echinoderms can destroy the kelp beds if their natural predators don�t keep them in check.
