During Dive 13 of the 2021 North Atlantic Stepping Stones expedition, this dandelion siphonophore was seen at a depth of 2,447 meters (8,028 feet). Dandelion siphonophores are unusual and unique siphonophores because they anchor themselves to the seafloor using their tentacles. In this video, you can see the multiple threads attaching the animal to the seafloor and it appears to be potentially throwing out more threads or spawning.
