Developmental 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...
متن کاملMolecular phylogeny and biogeographic history of the European Maja spider crabs (Decapoda, Majidae).
We have assessed for the first time the phylogenetic relationships and biogeographic history of the crabs of the genus Maja that inhabit European coasts: M. brachydactyla, M. crispata, M. goltziana and M. squinado. Using mitochondrial markers, we have recovered a well-resolved phylogenetic tree that supports a single origin for the European species, most likely from an Indo-West Pacific ancesto...

The crustacean exoskeleton presents several functions including the stabilization of the whole body of the animal, resistance to mechanical loads, and protection to the environment and against predators [1]. The structure of crustacean exoskeleton consists of an organic matrix constituted by α-chitin, proteins and carotenoid pigments and an inorganic fraction where calcium carbonate is the main...
