New Jellyfish Species with Potential Unique Venoms Discovered Near Japan

The Santjordia pagesi, distinguished by a bright red cross, raises hopes for novel venom discoveries and highlights conservation needs.

A new jellyfish species, Santjordia pagesi, discovered near Japan's Ogasawara Islands, may possess unique venoms previously unseen in jellyfish.
Named the St. George's Cross Medusa, the species is distinguished by a bright red cross on its body, resembling the English flag's Cross of St. George.
The jellyfish was found in the deep-sea Sumisu Caldera, a hydrothermally active volcanic structure, and is notable for its relatively small size and approximately 240 tentacles.
Scientists believe the jellyfish's bright red stomach acts as a shield to hide its bioluminescent prey from predators.
The discovery raises the possibility of new venoms and underscores the importance of preserving the species and its habitat.
