Majorca Types Of Jellyfish

Jellyfish are invertebrates that present special cells used to capture prey and defend themselves.

These cells have a poisonous capsule inside.

When a prey or predator makes contact with the jellyfish, the capsule opens and the cells stick to them, injecting poison.

Our jellyfish sting remedies are good to know beforehand.

Jellyfish are usually transparent as they are 95% water, allowing them to camouflage easily.

Below you’ll find images and descriptions of the common types of jellyfish found around Majorca, Spain.

They usually live 20 to 40 miles from the coast where the water is saltier and warmer.

If it has been a dry winter and rainfall has been low, the water at the beach may be of similar salt levels, thus providing a favourable environment for jellyfish.

However, the main causes for an increase of jellyfish in an area are the marine currents and overfishing, especially when tortoises are captured, as these are the main jellyfish predators in the Mediterranean.

In Spanish, the word for jellyfish is medusa, like the mythical Greek monster with snakes for hair.

If you hear somebody saying that when you are in the sea or on the beach, be careful!

What to do if there are jellyfish at the beach?

As you can see, there are many types of jellyfish found in the Mediterranean around Majorca.

In most cases, you won’t come across any whilst enjoying the sea, but if you do:

  1. Do not get in the water, keep an eye on the shore too.
  2. If one jellyfish is spotted, there will probably be more around.
  3. Do not touch them even when they appear dead.
    It takes 24 hours for the sun to deactivate its poison.
  4. If stung:
    1. Do not scratch the skin with sand or a towel.
    2. Do not pour fresh water over the affected area.
    3. Apply ice for 15 minutes. Ice must be inside a plastic bag to avoid freshwater melting onto the affected area. If the area is still painful, seek medical attention.

Are the jellyfish in Mallorca poisonous?

Many of the jellyfish around Mallorca do inject poison when they come in contact with other animals, including humans.

This is more commonly referred to as being stung.

Typically, the sting is just painful with no long-term implications rather than lethal, however, people who are allergic should be very careful, as the stings could be lethal.
