Seattle’s Floating Jewels: A Guide to Local Jellyfish Species

Seattle’s Puget Sound is home to a surprising variety of jellyfish, from the moon jelly’s gentle pulse to the lion’s mane jelly’s impressive size. These gelatinous creatures drift through the waters, playing an important role in the marine ecosystem. Let’s explore some of the common jellyfish species you might encounter in and around Seattle.

Common Jellyfish of the Puget Sound

Moon Jelly (Aurelia labiata)

Perhaps the most frequently seen jellyfish in the Puget Sound, the moon jelly is easily identified by its translucent, saucer-shaped bell and short tentacles. They are generally harmless to humans, possessing only mild stinging cells. Moon jellies feed on plankton and small organisms, making them an important part of the food web. Large aggregations, or blooms, are common, especially during the warmer months.

Lion’s Mane Jellyfish (Cyanea capillata)

This is one of the largest known species of jellyfish. While their name might evoke fear, encounters are rare in the immediate Seattle area, but they are found in the Puget Sound. The Lion’s Mane is identified by its reddish-brown bell and long, trailing tentacles that resemble a lion’s mane. These jellies can deliver a painful sting, so caution is advised. You can read more about Lion’s Mane Jellyfish on Wikipedia.

Water Jelly (Aequorea victoria)

Also known as the crystal jellyfish, the Water Jelly is a bioluminescent species. It’s another common species of jellyfish in the Pacific Northwest. Its ability to glow in the dark makes it a fascinating subject for scientific research. These jellyfish are transparent and difficult to spot, but their bioluminescence can be seen on dark nights. The protein responsible for this bioluminescence, green fluorescent protein (GFP), has become a valuable tool in biological research. It is generally considered harmless to humans.

Egg-Yolk Jelly (Phacellophora camtschatica)

The Egg-Yolk Jelly is named for its distinctive yellow-orange center, resembling an egg yolk. It can grow to be quite large, and its tentacles are relatively short and stubby. This jellyfish feeds on other jellyfish and zooplankton. They’re found in various locations worldwide including Puget Sound.

Sea Nettle (Chrysaora fuscescens)

Although less frequently seen in the immediate Seattle area compared to moon jellies, Sea Nettles can be found in the wider Puget Sound. They have a golden-brown bell and long, flowing tentacles. Their sting can be painful, so it’s best to avoid contact. They feed on zooplankton, small fish, and other jellyfish. Their population fluctuates throughout the year.
