Seattle Stinging Jellyfish: What You Need to Know
Seattle’s Puget Sound is home to several species of jellyfish, some of which can sting. While not generally life-threatening, these stings can be painful and cause localized reactions. Understanding which jellyfish are present and how to react to a sting is essential for enjoying the waters around Seattle safely.
Common Stinging Jellyfish in Puget Sound
Several jellyfish species found in the Puget Sound are capable of stinging. The most common include:
Moon Jelly (Aurelia labiata)
Moon jellies are easily recognizable by their translucent, saucer-shaped bell. While they do possess stinging cells, their stings are typically very mild and often unnoticeable to humans. They are among the most abundant jellyfish in the Sound.
Lion’s Mane Jellyfish (Cyanea capillata)
The Lion’s Mane Jellyfish is the largest known species of jellyfish. These can occasionally be found in Puget Sound. They are easily identified by their reddish-brown or yellowish bell and long, trailing tentacles. Lion’s Mane jellyfish can deliver a potent sting, causing significant pain and skin irritation.
Water Jelly (Aequorea victoria)
Also known as crystal jelly, these jellyfish are bioluminescent. Water Jellies are more common in the open ocean but can be found in the Puget Sound and are not harmful to humans.
What to Do if Stung
If you are stung by a jellyfish in Puget Sound, follow these steps:
- Rinse the affected area with seawater. Avoid using freshwater, as it can worsen the sting.
- Remove any visible tentacles with tweezers or gloved hands.
- Apply vinegar to the sting site for at least 30 minutes. Vinegar helps neutralize the stinging cells of many jellyfish species.
- Apply a cold pack or ice wrapped in a cloth to reduce pain and swelling.
- If pain persists or you experience systemic symptoms (difficulty breathing, chest pain, muscle cramps), seek medical attention immediately.

Prevention
The best way to avoid jellyfish stings is to be aware of your surroundings. Avoid swimming in areas where jellyfish are known to be abundant. Wearing protective clothing, such as a wetsuit or rash guard, can also help reduce the risk of stings.
