La Manga is one of the main tourist areas in Spain with many British travelers visiting the region each year. The surroundings of Mar Menor are also popular with British expats.

One resident told a local Spanish newspaper: “The beaches of Galua and Marchamalo are teeming with them. I have lived here for 40 years and have never seen so many.

An expert from the Cartagena Oceanographic Research Institute said: “Something similar happened four years ago in the port of Cartagena and schools of this species often appear in Cabo de Palos and Calblanque, but I have never seen so many in this region.

Jellyfish belonged to the Pelagia noctiluca species and are quite small but have a strong sting.

They are purple in color, which has earned them the nicknames ‘Mauve Stinger’ and ‘Purple people-eater’.

DO NOT MISS

Jellyfish are covered in stinging cells and are even able to sting for a short time after death.

A sting from one of the purple creatures usually results in pain that lasts one to two weeks, redness, and a rash.

Although it is painful, it is generally not very dangerous and there are no known deaths from this species of jellyfish.

In very rare cases, the jellyfish sting can leave a scar if the sufferer has an allergic reaction to the attack.

Cartagena City Hall is responsible for the area and has confirmed it will remove the jellyfish on December 20.

Unvaccinated British tourists are currently prohibited from traveling to Spain, as all Britons must be fully vaccinated to enter.

British tourists returning from Spain to the UK must pass a pre-departure test before arriving in the UK.

They should then take a PCR test no later than the second day after travel and self-isolate until they receive the result.
