The beaches of the city of Guardamar del Secure, in southeastern Spain, were closed this last week after two poisonous marine slugs were found in the water, according to local authorities.
The Guardamar Police Force explained, in Facebook publication, that the “blue dragon”, as the animal is popularly known, is only 3 centimeters, but feeds on jellyfish and is able to absorb their poison, enhancing it and can paralyze animals 300 times its size.
“Contact with this marine animal can be dangerous and cause painful burns on the skin,” said police, who advised that bathers have “extreme care” to avoid this contact.

The interdiction lasted two days, but the alert is still in force. The mayor of the city, José Luis Sáez, advised that anyone who is burned should clean the wound with seawater and seek medical attention immediately.
The Guardamar region is one of Spain’s most famous sights. The “blue dragons” are hardly seen in the Mediterranean, being more common in the waters of the Atlantic and the Pacific.
