Muggiaea atlantica

Species of hydrozoan

Muggiaea atlantica is a species of small hydrozoan, a siphonophore in the family Diphyidae. It is a cosmopolitan species occurring in inshore waters of many of the world's oceans, and it has colonised new areas such as the North Sea and the Adriatic Sea. It is subject to large population swings, and has been held responsible for the death of farmed salmon in Norway. The species was first described by J.T. Cunningham in 1892 from a specimen obtained at Plymouth, England.
