sea spiders

Scientists have identified two previously unknown species of sea spiders along Canada's coastline. The discovery adds to knowledge of marine biodiversity in cold northern waters, where sea spiders — strange, long-legged arthropods that live on the ocean floor — are still poorly catalogued. Researchers say such finds highlight how much remains undiscovered in coastal ecosystems, and the announcement is drawing attention from marine biology and science audiences.
