The Pacific sea nettle (Chrysaora fuscescens), or West Coast sea nettle, lives in the eastern Pacific Ocean from Canada to Mexico.
The Pacific sea nettle is also known as the West Coast sea nettle, and brown sea nettle. It may be present in the open sea but generally it is found near the surface, drifting in byas, estuaries and lagoons. It is native to the Eastern Pacific Ocean from Canada to Mexico
Adult sea nettles have a distinctive golden-brown bell with a reddish tint and four extending oral arms and numerous maroon tentacles extending downward from around the perimeter of the bell. In this adult stage called a “ medusa “ the males and females release sperm and eggs in to the water. The fertilised eggs develop in to larvae which drift and settle on the sea floor and become small polyps. The polyps remain dormant throughout winter and then during Spring ans Summer they “bud off” as tiny sea nettles to grow quickly in to adults
