Post-larval development and sexual dimorphism of the spider crab Maja brachydactyla (Brachyura: Majidae)
the post-larval development of the majid crab Maja brachydactyla Balss, 1922 was studied using laboratoryreared larvae obtained from adult individuals collected in the ne atlantic. the morphology of the first juvenile stage is described in detail, while the most relevant morphological changes and sexual differentiation are highlighted for subsequent juvenile stages, until juvenile 8. the charac...
متن کاملA new species of Naxia Latreille, 1825 (Brachyura: Majidae) from deep water off Brazil.
A new species of spider crab, Naxia atlantica n. sp., is described and illustrated from deep waters off São Paulo (southeastern Brazil). The new species can be separated from its congeners by a suite of characters including shapes of the propodi of the walking legs, rostrum and basal antennal article. This is the first record of the genus outside southern Australia and New Zealand.
متن کاملComplete Larval Development of Two Species of the Asian Crab Genus Pseudosesarma (brachyura: Thoracotremata: Sesarmidae)
The complete larval development of the sesarmid crabs Pseudosesarma bocourti (A. Milne-Edwards, 1869) and P. moeschii (de Man, 1892) was obtained through laboratory culture. The previously unknown larval stages of both species, consisting of four zoeal stages and a megalopa, are morphologically almost identical and thus described and illustrated as one.The morphology of the zoeae and megalopae ...

متن کاملDevelopmental and moult cycle related biochemical changes in larvae of the spider crab, Maja brachydactyla (Brachyura: Majidae) - Cambios bioquímicos relacionados con el ciclo de muda y desarrollo en las larvas del cangrejo, Maja brachydactyla (Brachyura: Majidae)
Ontogenetic changes in dry weight, elemental composition (CHN), and digestive enzyme activities (total protease, amylase) were studied during the moulting cycle of all larval instars (zoea I-II, megalopa; ZI, ZII, M) of the spider crab Maja brachydactyla Balss, 1922 reared in the laboratory. A gradual but significant increase in biomass was observed throughout the zoeal instars, followed by ste...
