Geryonia proboscidalis

Geryonia proboscidalis is a pelagic species found in tropical and subtropical waters, including the Indo-Pacific, Atlantic Ocean, and the Mediterranean. This jellyfish can reach a maximum length of 8.0 cm. It is typically encountered in open water, often at depths shallower than 40 meters, with a significant number of sightings occurring at dive sites within this range. The species is primarily observed in the medusoid stage of its life cycle, which is the stage divers are likely to encounter during dives. Its translucent body and long, trailing tentacles can make it somewhat difficult to spot among the water column, but its unique shape helps distinguish it from similar species.  In terms of diet, Geryonia proboscidalis primarily feeds on zooplankton, utilizing its tentacles to capture prey. The reproductive behaviors of this species are not extensively documented, but it is known to reproduce in the medusoid stage. Encounters with this jellyfish can be intriguing, as they often drift gracefully through the water, providing divers with a unique experience. Geryonia proboscidalis has not been evaluated by the IUCN, and its conservation status remains unknown. However, it is recorded at several dive sites, indicating that it is relatively common in the areas where it is found.
