Jellyfish Invasion Catalan Bay Gibraltar
Individuals visiting Spain beaches this summer have been advised against going near Mediterranean coast has it is inhabited by a species of jellyfish which stings. Visitors are advised to be careful when they go to sea and take precautions against the stinging jellyfish. After ten years the Portuguese section of Man o’ War who are very deadly, they are not really jelly fish but consist of hydrozoans which are microscopic in floating colonies. They have been seen near the beaches surrounding Costa del Sol.
Their tentacles are sometimes longer than 30 yards, which stings ten times that of any other jellyfish; it’s more dangerous compared to the annual invasion of jellyfish in Mediterranean beaches.
In serious cases, its sting may result in heart failure to allergic victims. Scientists are afraid that the jellyfish might spread trough Spain coast and move to waters surrounding Balearic Islands when it has moved away from north Atlantic through Gibraltar.
Xavier Pastor who is a European director at Oceana ecological a campaigning group said that, The Portuguese deadly Man o’ War have been extinct for over a decade in Mediterranean, its sudden appearance at Spanish coast might be seen as a colonisation process which has occurred in various invading species. Also he said that we are not sure of what might be causing sightings but now we are looking at thousands.
Authorities in Spanish have started making provisions for defence in handling the jellyfish in the swarm around Mauve Stinger, they are light purple in colour and they emit yellow glow when it is night, they annually plague Mediterranean beaches.
Due to the effect of global warming also the excessive fishing by natural predators there is a rise in their numbers, every summer thousands of people on holiday are forced every time to seek medical attention for stings.
Scientists have predicted that total amount of jellyfish moving away from Spain coast this summer is said to be high, also steps have been taken to guard unsuspecting bathers.
Around 20 thousand people were treated in Catalonia northeastern region after the jellyfishes stung them; authorities used the satellite to locate the dangerous creatures.
Fishing boats are sent to scoop the jellyfishes when they come too close to the shore and move them far from the beaches.
Ministry of Spanish environment have started a campaign to warn bathers about the dangerous jellyfish and steps to take if a sting occurs. Mr Pasto said that swimming was at the individual personal risk. “The measures in place are as useful as treating cancer with a sticking plaster. Until we tackle the environmental issues that are causing the proliferation of jellyfish in Mediterranean waters the problem will only get worse.” Said Mr Pastor.
