Colobonema sericeum

Colobonema sericeum is a species of deep-sea hydrozoan in the family Rhopalonematidae that was first described in 1902.[1] This semi-transparent organism is found in the mesopelagic zone, has 32 tentacles, and has a bell diameter of up 45 mm.[2][3] They are holoplanktonic and never attach to the seafloor as part of their polyp life cycle, but instead have embryos that develop directly into a small, swimming medusae.[3]
