Jellyfish – what is worth knowing about Baltic species?

What species can be found in the Polish sea, and what to do if you come into contact with a jellyfish? Here is a guide that will answer these questions.

Species of jellyfish in the Baltic Sea

In the Polish waters of the Baltic Sea, you can find mainly 2 species of jellyfish:

• The blue jellyfish is one of the most characteristic species of jellyfish in the Baltic Sea. Recognizable due to its bluish colour and transparent body. This species  is known for forming large groups, especially in the warmer months of the year and usually only appears when the water has had time to warm up.
• A less common species of jellyfish is the festoon jellyfish, which has characteristic wavy edges of its body, which can take on various colours from transparent to pinkish. Unlike the blue jellyfish, the jellyfish is more likely to be found deep in the sea, but carried by sea currents, they also appear closer to the shore.

Can jellyfish in the Baltic Sea be dangerous?

The blue jellyfish, which most often appear in the summer, are safe for humans and do not cause skin burns. In winter, along the Polish coast, we can encounter the lionfish, the burn of which can be quite painful and require medical attention, especially in younger people.

What to do after being stung by a jellyfish, and what to avoid?

• If you come into contact with a jellyfish, it is important to act quickly to reduce discomfort.
• First of all, get out of the water as soon as possible.
• Do not rub the burn so as not to spread the venom throughout the body.
• If you are on a guarded beach, look for a lifeguard as soon as possible.
• You should use (if you have it with you) antihistamines in the form of ointments or gels, which will soothe swelling and reduce itching.
• Seek medical attention if the symptoms are severe, or the reaction seems allergic, it is recommended to consult a doctor.

Remember not to do the following:

• Do not touch the burnt area with your bare hand. This causes the venom to be spread over the entire surface of the body.
• Do not make sudden movements. This is also how the venom is distributed throughout the body.
• Do not wash the wound with fresh water or alcohol, do not apply ice. This activates the stinging cells and causes the burn to become more severe and the body to become poisoned.
• Jellyfish in the Baltic Sea are usually not dangerous, but it is worth being careful, especially when swimming in places where they may occur. We never know what exactly we are dealing with, so a good rule should be not to touch any wild animals in the water.
• Respecting the natural environment of marine organisms is crucial not only for our safety, but also for protecting these delicate creatures that play a specific role in the marine ecosystem. Knowledge about these creatures and appropriate precautions will certainly help you spend time safely and pleasantly by the Baltic Sea.
