Colobonema sericeum is found in many regions of the world. Compared to a lot of jellies, it’s a strong swimmer. It’s equipped with 32 tentacles. When disturbed, its tentacles light up (bioluminescence) and can drop off, confusing a would-be predator. Scientists suspect that Colobonema can re-grow the dropped tentacles, since they often observe this jelly with tentacles of different lengths. (source)
A deep sea bioluminescent squid, Planctoteuthis, inks and swims away from the ROV (remotely operated vehicle) during the Monterey Bay Aquarium Research Institute’s Bioluminescence and Biodiversity Expedition in October of 2012. It is not understood why this small squid has such an elaborate tail structure.
