Hydrozoans, scyphozoans, larvaceans and ctenophores observed in situ at hadal depths
Abstract Hydrozoa, Scyphozoa, Larvacea (Appendicularia) and Ctenophora are not typically associated with hadal communities. Here, we report observations of these groups based on 136 benthic camera lander deployments that spanned all five oceans, encompassing 14 deep sites, culminating in >100...
