They also have protective covers over their eyes that protect that area of the body as well from the sting or toxins that a Jellyfish may be able to deliver.

According to studies that have compiled the application of this protein in the field of medicine, thanks to this protein it has been possible to investigate biological processes in human cells, related to the propagation of cancer cells and the formation of new neurons. This marine invertebrate achieves such an expansion of its mouth that it can swallow other jellyfish or prey twice its own size. In 1961, Shimomura and Johnson isolated the protein aequorin, and its small molecule cofactor, coelenterazine, from large numbers of Aequorea jellyfish at Friday Harbor Laboratories. dsyoung @ sd61.bc.ca, Visit Shaw Centre for the Salish Sea The swordfish often lurks at the night, a time when they are more likely to scour the surface for food sources.
