Seattle’s Jellyfish: A Comprehensive Overview

Seattle’s waters are home to a surprising variety of jellyfish, ranging from the translucent moon jelly to the vibrant lion’s mane jellyfish. These gelatinous creatures play an important role in the marine ecosystem, but their presence also raises questions about their impact and the best way to observe them safely. Knowing the types of jellyfish found locally, their behavior, and potential dangers is key for anyone enjoying Seattle’s coastal areas.

Types of Jellyfish in Seattle Waters

The Puget Sound is a diverse marine environment, and that extends to its jellyfish population. Some of the most commonly seen jellyfish in the Seattle area include:

* Moon Jelly (Aurelia labiata): These are easily recognizable by their translucent, saucer-shaped bells and short tentacles. They are generally harmless to humans.
* Lion’s Mane Jellyfish (Cyanea capillata): This is the largest jellyfish species, and while less common than moon jellies, they can appear in the Puget Sound. They possess a powerful sting and should be avoided.
* Water Jelly (Aequorea victoria): Known for its bioluminescence, the water jelly is another common sight.
* Egg-Yolk Jelly (Phacellophora camtschatica): This jellyfish is named for its yellow center. It feeds on other jellyfish and is typically found in deeper waters.

Jellyfish Blooms and Their Impact

Jellyfish populations can fluctuate, leading to blooms, where large numbers congregate in specific areas. These blooms can impact the ecosystem by consuming large quantities of plankton and other small organisms. They can also affect human activities such as fishing and recreation. While blooms are a natural occurrence, changes in ocean conditions, such as temperature and nutrient levels, can influence their frequency and intensity.

Are Seattle Jellyfish Dangerous?

The danger posed by jellyfish in Seattle varies by species. Moon jellies are essentially harmless, while the lion’s mane jellyfish can deliver a painful sting. It’s always wise to exercise caution when encountering jellyfish. Avoid touching them, even if they appear dead, as their stinging cells may still be active. In the event of a sting, rinse the area with seawater (not freshwater) and remove any visible tentacles. Seek medical attention if symptoms worsen.
