Species such as the poisonous nomad jellyfish, the highly invasive Atlantic blue crab and the toxic silver-cheeked toadfish can now thrive in the Mediterranean, particularly in hotspots like Sicily and Greece.

How governments and communities deal with this problem is a litmus test, highlighting the immense challenges faced as we adapt to a warming world.
