Lysmata seticaudata (Decapoda,Crustacea) als Putzergarnele im Mittelmeer

Members of the shrimp speciesLysmata seticaudata were observed to clean a morrey eel in the western Mediterranean Sea (Baleares, Spain). In contrast to the cleaning symbiosis of tropical shrimps, severalLysmata species have only one host, thus representing a primitive type of cleaning behaviour.Lysmata seticaudata is not dependent upon cleaning for food and usually these shrimps are found without a host.
