If you are diving in the Med this summer watch out for the jellyfish. Huge swarms of the animals are invading coastal waters. Some Spanish beaches have been closed, but Sicily and North Africa are also reported to be badly affected.

Marine biologists blame hot dry weather for bringing jellyfish closer to the shore, and say overfishing may be increasing jellyfish numbers. At the same time, populations of jellyfish predators such as tuna and turtles are diminishing.

If you are stung wash the wound with sea water (not fresh) and apply an icepack inside a plastic bag.
