The red and blue jellyfishes
Very common toward the end of summer, the red jellyfish can be a menace. It stings and burns like a nettle if the tentacles are touched, but there are a lot of tentacles so it can hurt quite a bit. But not very dangerous unless there is an allergy case.Vinegar kills off the effect of the burns.Look out before you dive in, and in the high season, perhaps use a surfer's shirt or normal t-shirt.The blue variety hurts more, but is found in deeper water and they are rarely as many as the red ones. But it can be mistaken for the glassy jellyfish, which children like to play with.
