As a tourist or digital nomad, you may find yourself working from the stunning beaches of Gran Canaria. While the crystal-clear waters and golden sand may seem inviting, it is important to be aware of the dangers that can lurk beneath the surface. One of the most significant risks in these waters is the Portuguese Man o’ War, a venomous marine creature that can cause serious harm to humans. In this article, we will provide you with a comprehensive guide to this dangerous creature, including information on why and when they wash up on the beach, how to recognize them, how authorities warn for them, and whether or not they are dangerous.

What is a Portuguese Man o’ War?

The Portuguese Man o’ War (Physalia physalis) is not actually a single creature, but a colony of four different types of organisms known as zooids. These organisms work together to create the distinctive blue, purple, and pink float that is commonly seen on the surface of the water. Below the float are long tentacles that can stretch up to 50 meters in length. These tentacles are lined with stinging cells, which are used to capture small fish and plankton for food, and to protect the colony from predators.

Why and when do they wash up on the beach?

Portuguese Man o’ War are often seen washed up on the beach during the summer months, particularly after storms or periods of strong winds. This is because they are at the mercy of the currents, which can push them onto shore. In addition, the float of the Portuguese Man o’ War is filled with gas, which allows it to remain on the surface of the water. However, if the gas is depleted, the creature may become stranded on the beach.

How to recognize a Portuguese Man o’ War

It is essential to be able to recognize a Portuguese Man o’ War, as their stings can be extremely painful and potentially deadly. The most distinctive feature of the creature is its float, which is often mistaken for a jellyfish. However, while jellyfish have a bell-shaped body and short tentacles, the Portuguese Man o’ War has a long, thin float and long, trailing tentacles. The tentacles can vary in length, from a few centimeters to up to 50 meters, and can be almost invisible in the water. The tentacles are lined with small, purple or blue-colored sacs, which contain the stinging cells.

How do Authorities Warn for Portuguese Man o’ War?

If Portuguese Man o’ War are spotted in the area, a white flag with purple jellyfish will be raised as a warning. Keep an eye out for the flag and be cautious if you see it. If there is a significant infestation of jellyfish, it may also be reported in the local news. Stay informed and take necessary precautions to stay safe.

Are Portuguese Man o’ War dangerous?

In short, yes, Portuguese Man o’ War are dangerous. Their stings can cause a range of symptoms, from mild irritation to severe pain, swelling, and even death. The severity of the sting depends on a number of factors, including the size of the victim, the amount of venom injected, and the location of the sting. If you are stung by a Portuguese Man o’ War, it is essential to seek medical attention immediately. Do not attempt to remove the tentacles yourself, as this can cause further damage.
