STAUROMEDUSAE UK

An online guide to the Stalked jellyfish (Stauromedusae) found
around the coastal waters of the United Kingdom and Ireland.
Includes notes on their identification, and where and how to find them.

Photographic guide to important plant and algal species
Many species of algae are import for stauromedusae. Some species of stauromedusae are fairly cosmopolitan but other species are most likely found on a limited number of algal species. The following is a guide to species on which stauromedusae are usually found. This is not a definitive list and more species will be added in time, but the most important species are most likely to be added already. The marine plant species Zostera marina, or Eelgrass is of great importance.
