Scientists at the University of Cambridge have found a link between the ocean-dwelling Hallucigenia and modern velvet worms, a small group of animals that live in tropical rain forests. Hallucigenia was discovered in Burgess Shale in Canada’s Rocky Mountains and was so named because it looked weird and people did a
