Lebbeus groenlandicus is a shrimp species indigenous to the Dokdo islands in the East Sea of Korea. We report the 17,399 bp mitochondrial genome (mitogenome) of the species that consists of 13 protein-coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and a control region (CR). A maximum-likelihood tree, constructed with 18 prawn and 45 shrimp mitogenomes, confirmed that L. groenlandicus occupies the most basal position within the Caridea infra-order and is closely related to Pandalidae shrimps.

The biochemical composition of muscle from three deep-sea animals, Tanaka's eelpout Lycodes tanakae magistrate armhook squid Berryteuthis magister, and ocean sunfish Mola mola caught in the East sea in South Korea was determined. The moisture (81.4-93.8 g/100 g), crude protein (5.0-15.6 g/100 g), crude lipid (0.1-1.5 g/100 g), and ash (1.0-1.1 g/100 g) contents of the two fishes were analyzed. The proximate composition of magistrate armhook squid was: moisture 84.0 g/100 g, crude protein 12.4 g/100 g, crude lipid 0.7 g/100 g, and ash 1.5 g/100 g. There was little difference in the proximate compositions of the three animals. The total amino acid contents of Tanaka's eelpout, magistrate armhook squid, and ocean sunfish were 14.64, 10.75, 3.10-9.95 g/100 g, respectively. High levels of glutamic acid, aspartic acid, lysine, leucine, and arginine were found, while low levels of histidine, glycine, and cysteine were detected in the animals. A survey of the free amino acid contents of the animals revealed large amounts of alanine and glycine. Significant differences were found in the fatty acid composition among the three species. Specially, different saturated fatty acids (17.14-40.49%) such as C16:0, and C18:0, monounsaturated fatty acids (19.19-46.88%) such as C16:1, and C18:1, and polyunsaturated fatty acids (35.41-57.08%) such as EPA, and DHA was identified. Our results suggest that each of these deep sea animals possesses nutritional value and should be considered as a foodstuff.

Animal Systematics, Evolution and Diversity

“…The hippolytid genus Lebbeus currently contains 61 species in the world (De Grave and Fransen, 2011;Komai, 2011;Komai et al, 2012;Nye et al, 2012), of which only four species have been reported from Korean waters (see The Korean Society of Systematic Zoology, 1997; Cha et al, 2001;Kim et al, 2007Kim et al, , 2010: Lebbeus groenlandicus (Fabricius, 1775), L. grandimana (Brashnikov, 1907), L. unalaskensis (Rathbun, 1902), and L. polaris (Sabine, 1824). Two species of hippolytid shrimps collected in a scallop farm of Jumunjin, Gangneung, and in Gampo, Gyeongju, by SCUBA diving to a depth of approximately 15 m, were identified as Lebbeus speciosus (Urita, 1942) and Lebbeus comanthi Hayashi and Okuno, 1997, respectively.…”

Two species of the hippolytid shrimps, Lebbeus speciosus and Lebbeus comanthi, are described and illustrated for the first time in Korea. They were collected from the East Sea. Lebbeus speciosus was found in a scallop farm of Jumunjin, Gangneung, and L. comanthi associated with crinoids, was found in Gampo, Gyeongju. The difference between these two related species is in the number of dorsal teeth of the rostrum, five teeth in L. speciosus and a single tooth in L. comanthi. The Korean Lebbeus species has increased to 6 species by the present report. They are L. grandimana, L. polaris, L. unalaskensis, L. groenlandicus, L. speciosus, and L. comanthi
