Photograph by @paulnicklen // A sunflower seastar (Pycnopodia helianthoides) works stealthily across the ocean floor in search of food. They can grow up to 3 feet in diameter and travel at rip roaring speeds of 3 feet a minute as they seek out sea urchins. Water temperatures off the coast of the US and Canada have warmed by several degrees and tragically, this starfish species was the hardest hit from an aptly named disease called “starfish wasting disease”. I took this image several years ago when this species was everywhere. Now, they have all but vanished from this coast. #climatechange #warmingoceans
