About Olindias muelleri Haeckel, 1879
Olindias muelleri Haeckel, 1879 (with the synonym Olindias phosphorica) is commonly called the cigar jellyfish. It is a species of hydrozoan found in the central and eastern Atlantic Ocean, and the Mediterranean Sea. Because the Mediterranean Sea is mostly a warm body of water, this jellyfish is classified as a warm-water species. Global warming has helped this species increase its population and spread throughout the Mediterranean Sea.
