Can Jellyfish Sting Through a Wetsuit

Jellyfish are floating medusae that have a bell-shaped body and long, trailing tentacles. Most jellyfish sting humans when they come into contact with their tentacles, which contain stinging cells called cnidocytes. These stinging cells are used by jellyfish to capture prey and protect themselves from predators. When a jellyfish stings a human, the cnidocytes discharge their poisonous contents into the victim’s skin. In most cases, the sting is not serious and causes only temporary pain and skin irritation. However, some jellyfish species have venomous stings that can be deadly to humans.

Wetsuits are made of neoprene, a synthetic rubber material that is impermeable to water. This means that when you are wearing a wetsuit, you are effectively surrounded by a layer of material that jellyfish stingers cannot penetrate. In other words, a wetsuit will protect you from being stung by a jellyfish.

There are two potential downsides to this protection: first, if you are stung while wearing a wetsuit, it may be more difficult to remove the stinging cells from your skin; and second, some types of jellyfish venom can cause an allergic reaction even if the stingers do not penetrate the skin. For these reasons, it is always best to avoid contact with jellyfish altogether.

What is a Jellyfish?

Jellyfish are a type of marine invertebrate animal, belonging to the phylum Cnidaria. Jellyfish are mainly free-swimming marine animals, but some live in freshwater environments. The body of a jellyfish is composed of three layers: an inner layer (gastrodermis), a thick middle layer (mesoglea), and an outer layer (epidermis). Jellyfish have a simple nervous system, and do not have eyes or other sense organs.

How do Jellyfish Sting?

Jellyfish have tentacles that are lined with special stinging cells. When something brushes up against the tentacle, the cells are triggered and fire tiny darts into the skin. These darts contains a venom that can cause a reaction ranging from a mild irritation to severe pain and even death, depending on the species of jellyfish. Some species of jellyfish can even sting through a wetsuit, so it’s important to be careful when swimming in waters where they are found.

What are the Symptoms of a Jellyfish Sting?

Most jellyfish stings only cause minor symptoms, such as redness, itching, and pain.However, some types of jellyfish can deliver a more serious sting. This is especially true if you have an allergy to the venom.If you’re stung by a jellyfish, you may have the following symptoms:

  • Pain that ranges from mild to intense
  • Swelling
  • Redness
  • Rash
  • Blisters
  • Headache
  • Muscle cramps
  • Nausea and vomiting

Some people may also experience an allergic reaction to a jellyfish sting. Symptoms of an allergic reaction can include:

  • Hives
  • Itching all over your body
  • Swelling of your face, lips, or tongue

Anaphylaxis is a rare but serious allergic reaction that can be caused by a jellyfish sting. Symptoms of anaphylaxis can include:

  • Tightening in your throat
  • Difficulty breathing
  • Dizziness
  • Fainting

If you have any of these symptoms after being stung by a jellyfish, call 911 or go to the nearest emergency room immediately.

How to Treat a Jellyfish Sting

If you’ve been stung by a jellyfish, there are a few things you can do to ease the pain and discomfort.

First, rinse the area with seawater (not fresh water) to remove any tentacles or bits of jellyfish that may still be attached to your skin. This will also help to remove any nematocysts (stinging cells) that may not have been discharged when the jellyfish first stung you.

Next, apply heat to the affected area. This can be done with a hot water bottle, a warm compress, or even by immersing the area in hot water (make sure it’s not too hot!). The heat helps to break down the venom and ease the pain.

If you don’t have access to heat, you can try applying vinegar or baking soda to the area. These home remedies help to neutralize the venom and provide some relief.

Finally, if the pain is severe or you have any other symptoms (such as difficulty breathing), seek medical attention immediately.

How to Prevent a Jellyfish Sting

Jellyfish stings can be painful, and in some cases, they can be deadly. If you are planning to go swimming in waters where jellyfish are present, it is important to take steps to prevent being stung.

There are several things you can do to reduce your risk of being stinged by a jellyfish:

  • Wear a wetsuit. A wetsuit will provide a barrier between your skin and the jellyfish, making it less likely that you will be stung.
  • Avoid touching jellyfish. If you see a jellyfish in the water, do not touch it. Even dead jellyfish can sting.
  • Do some research before you go swimming. Find out if there are any dangerous jellyfish in the area and what the best precautions are.
  • If you see signs warning of the presence of jellyfish, obey them. Do not enter the water until the danger has passed.

By following these simple tips, you can reduce your risk of being stung by a jellyfish.


From the above information, it appears that jellyfish can sting through a wetsuit. However, this is not always the case. It depends on the type of jellyfish, the thickness of the wetsuit, and whether or not the jellyfish is able to penetrate the wetsuit material. If you are concerned about being stung by a jellyfish, it is best to avoid them altogether.
