Purple-striped Sea Nettle

Chrysaora colorata

Also known as Purple-striped Jelly, Purple Striped Jellyfish

Purple-striped sea nettles drift through California coastal currents with striking silvery bells adorned with deep violet radial stripes. Their trailing oral arms and dark tentacles extend several meters below, ensnaring planktonic prey and small fishes with stinging cells. Young cancer crabs often hitch a ride on the outer bell, feeding on tiny amphipods while sheltered from open-water predators.

Why interaction risk is very high
Delivers a painful sting; avoid touching tentacles in the water or stranded on beaches.
Why it is dangerous
Nematocysts along tentacles inject toxins causing immediate burning pain, redness, and welts.
How to recognize a risky encounter
Look for a large silvery umbrella marked with distinct purple radial bands and trailing dark tentacles.
What to do
Maintain distance in ocean waters and never handle stranded specimens bare-rinse stings with saltwater or vinegar.
Responsible observation
