Chrysaora fuscescens
The large sea nettle jelly seems to have the ability to hypnotize us with their rhythmic undulations and the graceful spread of their lacy tentacles.
Although jellies like the sea nettle can propel themselves using a form of jet propulsion where they squeeze water through the bells of their bodies, they cannot move quickly or pursue other animals. They must feed as they drift on the ocean’s currents, spreading their tentacles out like nets to catch fish and other unsuspecting prey. Once an animal has been immobilized by the sea nettle’s sting, special tentacles called “oral arms” begin digesting it even before it has reached the jelly's mouth. Despite this potent sting, sea nettles present no real danger to human beings and are often eaten by seabirds and large fish.
Range and Habitat
Pacific sea nettles are particularly abundant off the Oregon and California coasts. In recent years, their numbers appear to be increasing dramatically which may be due to climate change.
Conservation Status
Common.
