Pacific sea nettles are beautiful, photogenic and fascinating to watch as they move aimlessly through the water. Utterly different than humans, they appear to be living a carefree life.

Jellies have an elementary nervous system, shaped like a net, throughout their bodies that can detect, light, smell and other stimuli. They cannot see or hear, however, and they never sleep. Jellies are comprised of about 95% water. In contrast, humans are about 65% water.

Off the Oregon Coast, sea nettle populations are increasing due to a reduction in predators, such as sea turtles and jelly-eating fish. Carnivorous themselves, their sting paralyzes their prey of other sea jellies, zooplankton and copepods.

The Oregon Department of Fish and Wildlife (ODFW) encountered swarms of pacific sea nettles two miles off shore at Depoe Bay. Enjoy watching their beautiful forms glide effortlessly through the water.
