The Legend of the depths

We don’t know a lot of things about what the abysses contain, and this box-jellyfish is the perfect proof. It is so rare and unknown that it does not have a name. This mysterious jellyfish came into contact with mankind only once in history. It defines the limit of our knowledge on the great depths abyssal.

This unnamed jellyfish is a box-jellyfish (Cubozoaire or Cubozoa), like the box-jellyfish of Australia (Chironex fleckeri) also known as « Navy sting », « Sea wasp » or « Hand of death ».

This unnamed jellyfish is a box-jellyfish (Cubozoaire or Cubozoa), like the box-jellyfish of Australia (Chironex fleckeri) also known as « Navy sting », « Sea wasp » or « Hand of death ».

Small, cube-shaped and possessing four tentacles, it produces its own natural light thanks to the bioluminescence. Since the light is totally non-existent in these dephts, this jellyfish uses this capacity to defend itself against predators by blinding them for a few seconds by projecting luminescent secretions.

Little known to scientists, and for cause, it lives between four and six kilometers deep in the absolute darkness. It is impossible to observe.

Thanks to the N.O.A.A. (National Oceanic and Atmospherique Administration), we can admire a picture of the jellyfish. It’s amazing when you know it’s only been seen once and it’s never been seen since. Unfortunately, it could not be recovered for its observation, so it does not have a scientific name yet or even vernacular (common name), and its classification remains unknown to date.
