We produced this video 4 years ago, at the very start of what has since become known as Sea Star Wasting Disease. The epidemic has wiped out nearly all sunflower sea stars up and down the west cost, from Alaska to California. British Columbia used to have blankets of sea stars walking around the ocean floor, devouring urchins, and well, just looking very pretty! Local diver Jonathan Martin talks us through the initial outbreak.
A good follow up video from National Geographic can be found here.
