The Chrysaora fuscescens (Pacific Sea Nettle)
The Pacific Sea Nettle is commonly found along the coasts of Oregon and California in the United States. Their "bells" are distinctively golden-brown with a reddish tint, and can grow larger then one meter, but are usually on 50 cm across. Their tentacles, or "arms", can be as long as ten feet, but their stings are not deadly to humans, only irritating. It is popular in public aquariums due to its attractive colors and easy maintenance.
an odd system
Common in almost all members of the phylum Cnidaria, the jellyfish doesnt have a proper circulatory system. Rather, it has what is known as a Gastrovascular System. This system meshes together the digestive system's job of gathering and breaking down food, as well as distributing nutrients throughout the body. With the Jellyfish, its tentacles act as food collectors. They bring their paralyzed prey up to their mouth, wherein after entering it is digested, and the nurtients are spread to the rest of the body.
