The carpet covered the Palavas-les-Flots beach, France, making the area turn into dark purple, Weather Network reported on April 11. Estimated number of jellyfish can reach billions. They can gradually stink after being stranded.

This is not an unusual phenomenon for sailing jellyfish, also called "sailors following the wind" . When spring comes, this jellyfish moves closer to the shore, so it is prone to storms and strong winds blow in. Sails often appear on American beaches, but this is the first time they have floated ashore in Palavas-les-Flots.

The jellyfish looks like jellyfish but actually each individual is a collection of many small creatures called hydro. Jellyfish mainly eat plankton. Their venom can irritate the eyes and mouth, so experts warn people to avoid direct contact.
