First zoeal stage of Macrocoeloma subparallelum ( Stimpson , 1860 ) ( Decapoda : Brachyura : Majoidea ) described from laboratory hatched material
Th e morphology of the fi rst zoeal stage of the decorator crab Macrocoeloma subparallelum (Stimpson, 1860) from Cuba is described and compared with the available descriptions for the genus. Among Macrocoeloma Miers, 1879 species, the fi rst zoea of M. subparallelum can be diff erentiated only by the number of aesthetascs and setae of the antennule (4 and 2, respectively). Recently, Macrocoelom...
متن کاملEriocheir sinensis, (Crustacea: Decapoda, Brachyura, Varunidae): fish egg consumption
Dispersal of Eriocheir sinensis from its native habitat is a worldwide concern. As one of the most invasive species known, this crab causes significant disruption to foreign ecosystems. In particular, populations in the United Kingdom (UK) are increasing in number and E. sinensis has been reported from many river catchments (www.mittencrabs.org.uk). The ecological implications of this invasion ...
متن کاملMorphology of the first zoeal stages of five species of the portunid genus Callinectes (Decapoda, Brachyura) hatched at the laboratory.
The genus Callinectes Stimpson, 1860 currently consists of 16 species, six of which are reported in Brazilian coast. In the present study, the first zoeal stages of Callinectes bocourti, C. danae, C. exasperatus, C. ornatus and C. sapidus from Brazil were obtained from ovigerous females. The morphological and meristic characters of all these larval stages are described and illustrated. Those of...
متن کاملDifferential toxicity of copper, zinc, and lead during the embryonic development of Chasmagnathus granulatus (Brachyura, Varunidae).
Ovigerous females of the estuarine crab Chasmagnathus granulatus were exposed to copper (0.01 and 1 mg/L), zinc (0.05, 1, and 10 mg/L), or lead (0.01 and 1 mg/L) during early, late, or whole embryonic development. None of the assayed heavy metals produced a significant mortality of females, neither a decrease in the number of hatched larvae nor a decrease in the egg incubation time, but several...
متن کاملRe-examination of the Zoeal Morphology of Chasmagnathus Granulatus, Cyclograpsus Lavauxi, Hemigrapsus Sexdentatus, and H. Crenulatus Confirms Consistent Chaetotaxy in the Varunidae (decapoda, Brachyura)
The morphology of rst stage zoea larvae of four species of grapsoid crabs (viz., Chasmagnathus granulatus Dana, 1851, Cyclograpsus lavauxi H. Milne Edwards, 1853, Hemigrapsus crenulatus (H. Milne Edwards, 1837), and H. sexdentatus (H. Milne Edwards, 1837)) from Argentina and New Zealand was re-examined. Special attention was given to those characters that have been recently recognized to sepa...
