Sightings of giant phantom jellyfish in the Antarctic Ocean : Although Stygiomedusa is not native to the Antarctic Ocean, there have been sightings of the jellyfish in the Antarctic Ocean [ 8 ] with the help of submersibles.
Upon reaching adult size, jellyfish spawn regularly if there is a sufficient supply of food. In most species, spawning is controlled by light, with all individuals spawning at about the same time of day; in many instances this is at dawn or dusk. [66] Jellyfish are usually either male or female (with occasional hermaphrodites).

As a guideline, nekton are larger and tend to swim largely at biologically high Reynolds numbers (>10 3 and up beyond 10 9), where inertial flows are the rule, and eddies (vortices) are easily shed. Plankton, on the other hand, are small and, if they swim at all, do so at biologically low Reynolds numbers (0.001 to 10), where the viscous ...
