A Pacific sea nettle (Chrysaora fuscenscens) floating near Port Hardy. These jellyfish are most often seen in late summer, when warm currents carry them up the coast as far as Alaska.
They play an important role in the ecosystem, feeding on plankton, small fish, and other jellyfish, while in turn providing food for sea turtles, seabirds, and larger fish.
Though their sting can be painful to humans, it isn’t considered dangerous. What’s most striking about them is their size—fully grown sea nettles can have bells nearly 18 inches across with oral arms that stretch more than 12 feet.
