On the reproductive biology of the deep-sea lobster, Polycheles typhlops (Decapoda, Palinura, Polychelidae), from the central-western Mediterranean

Data are provided related to the reproductive biology of a deep-sea lobster, Polycheles typhlops, caught in Sardinian waters between 400 and 1400 m depth. Analyses were performed on 1180 females and 935 males. In both sexes, the carapace length decreased markedly and regularly with increasing depth; the females proved to be prevalent at greater bathymetric depths. The temporal evolution of the gonadosomatic index, and of the percentage distribution of the various stages of ovarian development, did not reveal any clear seasonality in reproduction for the species

On the reproduction of Acanthephyra eximia s. I. Smith, 1884 in the central western Mediterranean

Macroscopic and histological analysis were performed on the female gonads of Acanthephyra eximia. The macroscopic observation regarding the changes of the ovaries leads us to identify six stages of development, validated by histological analysis

Biochemical composition of a mesobathyal lobster(Polycheles typhlops, Heller 1862 Decapoda, Palinura, Polychelidae)

To characterize some traits of the life strategies of Polycheles typhlops, a deep-sea small lobster usually encountered as by-catch within deep trawls in the Southern Tyrrhenian Sea (Mediterranean Sea), we analysed the biochemical composition of caudal muscles of 49 specimens collected in March and April 2007. Differences in the biochemical composition between females and males were weak, and relevant differences in protein (>90% of the organic C) and lipid (4-6%) contents were observed between developmental stages both in females and males. These differences were likely related to different food items and/or to the metabolic shifts associated with the reproduction. We argue that this deep-sea lobster could cover a relevant role in the meso-pelagic food webs and attract future commercial interests
