A phylogenetic analysis of all 17 extant species of the clawed lobster genus Metanephrops based on mitochondrial 12S rRNA, 16S rRNA and cytochrome c oxidase I, and nuclear histone H3 gene sequences supports the morphological groupings of two of the traditional groups of the genus (the binghami and japonicus groups) but refutes monophyly of the other ...

Enzyme polymorphism in three species of Metanephrops (Decapoda: Nephropidae) from Taiwan
Biochemical Systematics and Ecology, 1990Abstract Electrophoretic analysis of 22 genetic Loci coding for 17 enzymes was used to investigate relationships among three species of Metanephrops ( M. thomsoni M. formosanus and M. japonicus var ) from Taiwan. Eleven Ioci are identically monomorphic in the three species.

A New Record of Acanthacaris Tenuimana Bate (Decapoda, Nephropidae) From the Japanese Waters
Crustaceana, 1985Two specimens of the nephropid genus Acanthacaris collected from southwest of Kyushu, Japan were recently examined. They proved to belong to A. tenuimana Bate, which constitutes the first record for the Japanese fauna. The present paper presents short notes on these specimens, showing the range extension and some morphological variations of this rare ...

Maximum Size of Lobsters (Homarus) (Decapoda, Nephropidae)
Crustaceana, 1978[Presentation des donnees disponibles sur la longueur totale, la longueur de la carapace, la taille des pinces et le poids vif des plus grands homards connus, a savoir 20 provenant d'Europe, 25 d'Amerique et 9 du Cap. Alors que la taille maximale est sensiblement la meme pour les homards europeens et les homards americains, ceux-ci sont ...

A bilateral gynandromorph of Nephrops norvegicus (Decapoda: Nephropidae)
Marine Biology, 1972A bilateral gynandromorph specimen of Nephrops norvegicus (L.) from the Irish Sea is described. Previous records of gynandromorphs within the Nephropidae are discussed, together with other types of sexual abnormality found in N. norvegicus. It is suggested that the bilateral asymmetry is due to a chromosomal aberration in the first embryonic cleavage ...

Mitotic and meiotic chromosomes of the American lobster Homarus americanus (Nephropidae, Decapoda)
Hydrobiologia, 2001The chromosomes of H. americanus have been characterised by C-banding, fluorochrome banding and restriction endonuclease banding. Thanks to these techniques, it has been possible to identify mitotic and meiotic figures clearly and to study the distribution and structure of heterochromatic regions.

Reproduction in Nephrops norvegicus (Decapoda: Nephropidae)
Journal of Zoology, 1974During the period October 1969 to April 1972 a comprehensive study of the reproductive biology of the Norway lobster, Nephrops norvegicus (L. 1758), was made in the Irish Sea. Where possible comparison has been made with data from other areas. The results of the present investigation show that most females are berried annually, egg‐laying taking place ...

Age and growth in Nephrops norvegicus (Decapoda: Nephropidae)
Marine Biology, 1973The growth of the lobster Nephrops norvegicus (L.) in laboratory tanks was studied. The moult increments of males and females were not significantly different. The growth per moult was of the progressive geometric type throughout the life of the lobster, including the larval instars.

Feeding ecology ofNephrops norvegicus(Decapoda: Nephropidae)
Journal of Natural History, 1998The stomach contents of 248 Norway lobsters were analysed. Prey specimens were identified to the lowest taxonomical level possible. The frequency of occurrence method was used to analyse the data and the results are presented considering only major groups.
