Spanish media reported that specimens of the blue dragon have appeared on the island’s beaches FuerteventuraAnd while people should be vigilant in case they come across this species in the sea, it is no surprise that these dreaded mollusks arrive in these waters.

According to specialists, it is normal for these specimens to appear in the Canary Islands in the spring and autumn months, since they usually reproduce at these times. Being part of the plankton, its movement through the sea depends on the currents.

The blue dragon, whose scientific name is Glaucus atlanticus, is a gastropod mollusk of the order of the nudibrachia. Their size varies between three and four centimeters in length, and they are characterized by a silvery-blue coloration on their dorsal part and dark blue almost black stripes on their extremities.

Its appearance inspired the common name by which this species of sea slug is known, which, unlike mythological beings, does not fly, but rather travels through the waters of the South African, European, and Australian coasts, and also in waters temperate and tropical.

It is a poisonous animal because the toxins are obtained from its prey, mainly the purple sail and the Portuguese man-of-war. If a human comes into contact with the blue dragon, its venom can cause symptoms such as the following:

  • Sickness
  • Pain
  • Vomiting
  • Contact dermatitis
  • Erythema
  • Urticarial papules
  • Potential vesicle formation
  • Post-inflammatory hyperpigmentation
