Lion-maned jellyfish made a very successful arrival on the coasts of Wales. Difficult, indeed, to miss this venomous and potentially deadly species. This creature can measure up to 30 meters long with its filaments and its diameter oscillates between 50 centimeters and 2 meters, indicates the Daily Post .
The number of these animals is in strong increase in the area and those who beach beaches or rub shoulders with bathers at the beginning of summer vacation are becoming bigger.

Global warming in question
Testimonies reporting the presence of these giant seas are increasing in cities coastal areas of Llandudno, Anglesey, Conwy or Caernarfone (United Kingdom). Yet, although present throughout the northern hemisphere, lion-maned jellyfish usually move into colder waters in the North Atlantic or Scandinavia. "The million dollar question is: why is this happening? For now we do not really know, "says Peter Richardson, the head of the British marine conservation society.
For Maureen Midol, aquarium specialist in Brest (Finistère) cited by Ouest France the mbadive presence of slimy creatures is "a consequence of climate change. They are driven by the changing winds and currents. As the technician recalls, jellyfish do not choose the direction of their movements. They swim vertically and let the marine movements do the rest.
Earlier births
Climate change is also thought to be responsible for increasing the number of animals by helping to decimate their predators. The impact would also be felt on the size of the jellyfish. Thus, the rise in water temperature would trigger earlier births and a higher luminosity would aid the development of plankton as food.
With another problem, that of increased danger to animals . Because the more they are voluminous, the more the concentration of toxic venom they secrete is strong.
