Warty Jellyfish

Versuriga anadyomene

Versuriga anadyomene is a jellyfish characterized by its umbrella-shaped bell, which can reach a diameter of up to 600 mm. Its appearance features a gradient-like coloration that transitions from semi-translucent pink and purple at the center to brown at the edges. The bell is not entirely round or flat, but instead has pointed grooves that extend toward the center. To differentiate it from similar species, one can observe the distinct shapes of the male and female genital double somites and the structures of its appendages, including antennae and legs. Males tend to have a more slender body compared to females. This species is primarily found in nearshore waters of the Indo-West Pacific region, including locations such as Malaysia, the Philippines, Indonesia, Australia, and Vietnam. It thrives in warmer climates and has been recorded at various dive sites. Versuriga anadyomene is carnivorous, feeding mainly on drifting zooplankton. Its life cycle begins with an egg laid by an adult medusa, which develops into a free-living planula before attaching to a hard substrate and progressing through various life stages until it becomes a young medusa. Encounters with Versuriga on dives may be rare due to its infrequent sightings, but divers may observe its unique coloration and bell shape while exploring its habitat. This jellyfish plays an important role in its ecosystem, forming commensal relationships with other organisms and serving as prey for various marine predators. Despite its ecological significance, the species faces threats from human activities, including hunting, which can impact its population and the biodiversity of its environment.
