The enigmatic St. George’s Cross Medusa is a fascinating new species discovered in the depths of Tokyo’s southern waters. With its striking red cross, visible only from above, this jellyfish has captured the attention of marine biologists worldwide.

Measuring a mere 10cm in diameter, this translucent marvel, belongs to the family of umbrella-shaped jellyfish. Its red belly, reminiscent of the Cross of St. George, sets it apart in the vast oceanic expanse. Unlike typical species discoveries that involve collecting multiple specimens, researchers have struggled to obtain further samples of the St. George’s Cross Medusa. It is so rare that it has only been seen twice!

According to Professor Morandini, an esteemed expert in marine biology said the St. George’s Cross Medusa is unlike any other deep-sea jellyfish. “The species is very different from all the deep-sea medusae discovered to date. It’s relatively small, whereas others in this kind of environment are much larger. The bright red colouring of its stomach probably has to do with capturing food.”

So, the next time you find yourself gazing out at the ocean, remember that beneath the surface lies a world of wonders waiting to be uncovered. And who knows what other marvels, like the St. George’s Cross Medusa, await our discovery in the depths below.
