The discovery of a new jellyfish-like creature, named Physalia mikazuki, reflects the rapid changes in the ocean and marine ecosystems.
A creature resembling a flame jellyfish, with a striking blue color, has been discovered by experts off the coast of Japan. The appearance of this jellyfish, as well as its vibrant blue hue, is raising concerns about the rapid changes in the ocean impacting marine ecosystems. (Photo: goodgoodgood.co)
According to experts, the blue, fire-jelly-like creature has been identified as a new species, named Physalia mikazuki. This species is found in the waters off northern Japan, far exceeding its previously recorded range.

Researcher Kei Chloe Tan, who led the DNA analysis team, shared information about the new jellyfish species. He stated that morphological and DNA analyses revealed it to be an entirely new species, distinct from tropical fire jellyfish.

Regarding this incident, some
scientists speculate that unusual changes in ocean currents and rising sea temperatures may have caused the Physalia mikazuki jellyfish to drift to the area off the coast of Japan. Photo: cherylames.com.
Furthermore, changes in the intensity and direction of ocean currents are creating new "corridors," allowing marine life to move and settle in previously unrecorded ecosystems. Photo: cherylames.com.
Furthermore, experts suggest that the striking blue color of the new jellyfish species could be seen as a clear warning signal that the ocean is changing rapidly, with unpredictable ripple effects if humans do not take timely action.

Although no human injuries have been reported, the appearance of this new jellyfish species indicates a worrying change in the marine environment, posing significant risks to the underwater ecosystem and human life.
