Captive breeding / propagation

The offspring of Pseudothelogorgia hartogi are possible. Unfortunately, the number of offspring is not large enough to cover the demand of the trade. If you are interested in Pseudothelogorgia hartogi, please ask your dealer for offspring. If you already own Pseudothelogorgia hartogi, try breeding yourself. This will help to improve the availability of offspring in the trade and to conserve natural stocks.

Info

Unfortunately, there is very little information available about the gorgonian Pseudothelogorgia hartogi, including just two published water depth data of 18 meters and 57 meters.

The gorgonian was first described from the Arabian Sea by the coral specialist Dr. Leen van Ofwegen, who unfortunately died much too early, and named it Lignella hartogi.
The study material from 57 meters depth was collected by the R/V Anton Bruun expedition in the Indian Ocean in 1963 -1964.
Later the species was renamed by Frederick Bayer and has since been known as Pseudothelogorgia hartogi.

Etymology. The species name "hartogi" was chosen in memory of by Dr. Koos den Hartog, Curator of Coelenterata et al, at the National Museum of Natural History in Leiden, The Netherlands.

Synonym: Lignella hartogi van Ofwegen, 1990

  2. Ofwegen (1990) described the species Lignella hartogi based on material from the Arabian Sea (22°32'N, 68°07'E) from a depth of 57 m, collected by the R/V Anton Bruun expedition in the Indian Ocean in 1963-1964. At the time, he compared those samples with fragmentary material of L. richardii (Lamouroux, 1816) present in the Netherlands Centre for Biodiversity Naturalis (NCB Naturalis; Leiden, the Netherlands) and assigned the new species to the genus Lignella. Later, Bayer (1992: 506) concluded that the identity of the L. richardii could not be determined with any degree of certainty. Therefore, he established a new genus, Thelogorgia, and referred material previously identified as L. richardii to 1 of his 4 Thelogorgia species. However, Bayer did not reexamine L. hartogi. Subsequently, Ofwegen (1994) compared L. hartogi with species belonging to Thelogorgia and described a new genus Pseudothelogorgia, which included L. hartogi, based on differences in sclerites. Later P. hartogi was reported again by Dr. S.D. Cairns of the Smithsonian National Museum of Natural History (Washington DC, USA) who determined that material collected in Palau from a depth of 207 m belonged to this species (pers. comm.). Since then, it has not been reported until surprisingly the 1st author collected it at the Daymaniyat Is., Gulf of Oman (23°51'43.22"N, 58°6'15.16"E) at a depth of 18 m where it was photographed underwater, the 1st live photograph taken of Pseudothelogorgia (Fig. 1). The material is deposited in the NCB Naturalis (RMNH Coel. 39634). http://zoolstud.sinica.edu.tw/Journals/50.2/265.pdf Acknowledgments: The 1st author is most grateful to A.
