Morphology of the Larval Stages of Clibanarius Sclopetarius (Herbst, 1796) (Decapoda, Diogenidae) Reared in the Laboratory

Abstract

Nous avons étudié le développement post-embryonnaire de Clibanarius sclopetarius (Herbst, 1796) provenant de São Sebastiâo, État de São Paulo, Brésil. Les larves ont été élevées au laboratoire dans un milieu dont la salinité était de 35°/°° et la témperature de 25 ± 2°C, avec Artemia salina comme nourriture. Nous avons observé quatre ou cinq stades zoé avant le stade mégalope. Tous ces stades sont dessinés et décrits de façon détaillée. D'autre part, des comparaisons morphologiques sont faites entre les données obtenues ici et celles déjà connues pour d'autres espèces appartenant au même genre. L'étude de la morphologie des larves est du plus grand intérêt pour l'établissement des rapports phylogénétiques parmi les Crustacés.

Complete larval development of the hermit crabs Clibanarius aequabilis and Clibanarius erythropus (Decapoda: Anomura: Diogenidae), under laboratory conditions, with a revision of the larval features of genus Clibanarius

“…Lang and Young (1977) also concluded that the most common developmental series in C. vittatus involves five zoeal stages, with stage IV being separated from stage V by the lack of mandibular palp. The larval sequence in C. sclopetarius commonly includes four zoeal stages, and when a fifth zoeal stage appears, zoea III already exhibits a biramous antennule (Brossi-Garcia 1987). Due to the morphological similarity displayed by the fourth and fifth zoeal stages of C. sclopetarius, it seems that the occurrence of a fifth zoeal stage might result from a laboratorial artifact.…”

“…Brossi-Garcia (1987) compiled the larval morphological characters of most Clibanarius species described, and highlighted the conservative developmental pattern of the genus. Siddiqui et al (1991Siddiqui et al ( , 1993 confirmed the existence of this developmental pattern among Clibanarius species, but also noticed the occurrence of small intraspecific variations.…”

Larval Development of the Land Hermit Crab Coenobita Compressus H. Milne Edwards Reared in the Laboratory

“…Zoeal stages of Clibanarius and Petrochirus can be easily distinguished from C. compressus by their lack of lateral and dorsomedial spines on the abdominal somites and lack of anterolateral spines on the antennal scales (e.g., Provenzano, 1968b;Brossi-Garcia, 1987). Dardanus zoeae also lack dorsomedial spines on the abdominal somites and anterolateral spines on the antennal scales (e.g., Kurata, 1968;Hebling and Barros-Mansur, 1995).…”
