Chrysaora fuscescens is commonly found along the coasts of California and Oregon, though some reside in the waters north to the Gulf of Alaska, west to the seas around Japan and south to the Baja Peninsula. The populations reach their peak during the late summer.

Chrysaora fuscescens swim using jet propulsion by squeezing their bell and pushing water behind them, allowing them to swim against currents, although most of the time they prefer to simply float.



In common with other cnidaria, Chrysaora fuscescens are carnivorous animals. They catch their prey by means of cnidocyst (or nematocyst) - laden tentacles that hang down in the water. The toxins in their nematocysts are effective against both their prey and humans, though it is typically nonlethal to the latter. Because Chrysaora fuscescens cannot chase their prey, they must eat as they drift. By spreading out their tentacles like a large net, the sea nettle is able to catch food as it passes by. When prey brushes up against the tentacles, thousands of nematocysts are released, launching barbed stingers which release a paralyzing toxin into the quarry. The oral arms begin digestion as they transport the prey into the sea nettle’s mouth. Chrysaora fuscescens feeds on a wide variety of zooplankton, crustaceans, salps, pelagic snails, small fish as well as their eggs and larvae, and other jellyfish
