A species of sea anemone Sagartia elegans (Dalyell, 1848) (Anthozoa, Actiniaria, Sagartiidae) that is new for the Black Sea and is capable of clonal reproduction

A species of sea anemone Sagartia elegans (Dalyell, 1848) (Anthozoa, Actiniaria, Sagartiidae)... In the Black Sea, the sea anemone Sagartia elegans (Dalyell, 1848) has been found for the first time in the Gulf of Odessa (46°31′60 N, 30°48′ E) and karst caves and grottos of the Western Crimea (45°21′ N, 32°30′ E). Previously, S. elegans was known to inhabit coastal waters of Iceland, the British Isles, and continental Europe from Scandinavia to the Adriatic Sea. According to the available data, this gonochoristic species tends to asexual somatic reproduction through laceration: juvenile polyps develop from separated fragments of the pedal disc. A rich color polymorphism is observed. The numerous clonal populations that are found in caves consist of variously sized and similarly colored polyps. All of them descended from one parental individual. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Marine Biology Springer Journals

Abstract

In the Black Sea, the sea anemone Sagartia elegans (Dalyell, 1848) has been found for the first time in the Gulf of Odessa (46°31′60 N, 30°48′ E) and karst caves and grottos of the Western Crimea (45°21′ N, 32°30′ E). Previously, S. elegans was known to inhabit coastal waters of Iceland, the British Isles, and continental Europe from Scandinavia to the Adriatic Sea. According to the available data, this gonochoristic species tends to asexual somatic reproduction through laceration: juvenile polyps develop from separated fragments of the pedal disc. A rich color polymorphism is observed. The numerous clonal populations that are found in caves consist of variously sized and similarly colored polyps. All of them descended from one parental individual.
