Remarkable footage of a rarely seen giant deep sea jellyfish has been recorded by scientists.
Using a remotely operated vehicle (ROV), they captured a video of the huge Stygiomedusa gigantea.

The jellyfish has a disc-shaped bell than can be a metre wide, and has four arms that extend up to six metres in length.

Wow...diploblastic (http://en.wikipedia.org/wiki/Diploblastic) with no central nervous system. Instead, a nerve 'net' governs its behaviour. Cnidocytes (http://en.wikipedia.org/wiki/Cnidocyte) in its tentacles immobilizing prey, prey being conducted into its gastrovascular cavity for digestion, the pulsing of the medusa's 'bell' to provide motile force, all without anything remotely resembling a brain (or even ganglia)! They don't even possess true organs! Yet, they still get the job done. An ancient and highly efficient evolutionary paradigm for a metazoan. Amazing...
