Cigar Jelly

Olindias muelleri

Cigar Jelly, scientifically known as Olindias muelleri, is a hydrozoan species found primarily in the central and eastern Atlantic and the Mediterranean Sea. This jellyfish can be identified by its umbrella, which grows up to 8 centimeters in diameter and features 100-120 secondary tentacles along with 30-60 primary tentacles. Its stings are not particularly harmful, making it less intimidating for divers. The species thrives in warm waters, and its presence has increased in the Mediterranean due to global warming, which has facilitated its proliferation in these regions. Cigar Jelly typically inhabits pelagic environments and is commonly found in subtropical waters. While specific depth ranges are not detailed, divers can encounter this species in open-water settings. Its diet mainly consists of plankton, which it captures using its tentacles. The life cycle of Cigar Jelly involves a zygote developing into a planula, then into a polyp, and finally transforming into a free-swimming medusa. Encounters with Cigar Jelly during dives are generally safe due to their mild stings. Divers may observe these jellyfish gracefully drifting through the water column, adding to the underwater experience. Conservation status for this species has not been evaluated, indicating a need for further research regarding its population dynamics and ecological impact.
