The Pacific sea nettle is found in many of your West Coast national marine sanctuaries, including Olympic Coast National Marine Sanctuary. These cnidarians are related to corals and sea anemones.
Sea nettles sense light, which they use to travel from dark, deep waters to shallow, sunlit waters each day. What’s more:
A plastic bag or balloon floating in the water looks an awful lot like a sea nettle or other sea jelly. By keeping marine debris out of the water, we can help protect sea nettle predators – which in turn can help keep the ecosystem in places like Olympic Coast National Marine Sanctuary well-balanced!
