Why are they so many jellyfish?
” The arrival ” of jellyfish during Spring is determined by different factors. Some species like the « Aurelia » reproduce at this time of year. But climate conditions are the main factor ! From one year to another, there can be the same amount of individuals at sea; but these animals moving with the currents can be drown to the foreshore. The anticyclonic conditions of April 2017, with a quiet sea, have increased their presence on the French coasts. In addition, they move along with their food: plankton which follows currents. This abundancy doesn’t have any relation with the temperature of the summer!
