The bell is generally small, with an average diameter ranging from 2 to 6 inches.
The purple striped jellyfish features 4 oral arms and 8 long, slender stinging tentacles that can easily reach up to 16 inches.
Geographic range
The purple striped jellyfish is found in temperate and tropical waters around the world. It is especially common in the Mediterranean Sea and is notably observed along the coastlines during summer when environmental conditions favor its proliferation.
Habitat
Like all jellyfish and as its french name suggests, the purple striped jellyfish is a pelagic species that drifts with the currents.
When environmental conditions are favorable, it can form large aggregations, known as blooms, which can affect fishing activities and disrupt swimming near the shore.
Diet
The purple striped jellyfish feeds on plankton, small crustaceans, larvae, and other marine organisms that it captures with its long stinging tentacles.

Reproduction
Like all jellyfish, the purple striped jellyfish has a complex life cycle that includes several stages, including a larval stage and an adult stage.
It reproduces sexually, with internal fertilization of the female's eggs by sperm released into the sea by the male. The eggs are then released by the female through the jellyfish's mouth and develop into larvae before maturing into adult jellyfish.
Did you know ?
The purple striped jellyfish is highly stinging. Contact with the skin can cause painful stings that result in a burning sensation, skin irritation and allergic reactions in some individuals.
The stinging tentacles of the purple striped jellyfish are particularly thin and number eight, lining the bell
