Short summary
Unexpectedly, in sediment traps deployed in the Antarctic Amundsen Sea to catch small sinking particles in the water, large benthic invertebrates such as long and slender worms, baby sea urchins, and small scallops were found. We suggest three hypotheses: lifting of these animals by anchor ice formation and subsequent transport by ice rafting, spending their juvenile period in a habitat underneath the sea ice and subsequent falling, or their active use of the current as a means of dispersal.
