Reproductive biology of swimming crab, Charybdis hellerii (A. Milne-Edwards, 1867) in coastal waters of the Persian Gulf (Hormuzgan province)
This study was conducted to determine some aspects of reproductive biology of the Indo-Pacific swimming crab, Charybdis hellerii (A. Milne-Edwards, 1867) in coastal waters of the Persian Gulf (Hormozgan province) from June 2015 to May 2016. The results showed that the annual sex ratio is F: M=1:1.3, with 57.4 % males. All the five stages of ovarian development of C. hellerii were observed throu...
متن کاملRelative abundance and population biology of the non-indigenous crab Charybdis hellerii (Crustacea: Brachyura: Portunidae) in a southwestern Atlantic estuary-bay complex
Invasive species are potential threats to biodiversity, especially if they become established and outnumber native species. In this study, a population of the non-indigenous crab Charybdis hellerii was analyzed in an estuary-bay complex on the southeastern Brazilian coast, with respect to its abundance relative to sympatric native brachyuran species, as well as the size structure, sexual maturi...
متن کاملThe land crabs of the Discoplax longipes A. Milne-Edwards, 1867 species group, with description of a new species from Guam (Crustacea: Decapoda: Brachyura: Gecarcinidae).
Specimens of the gecarcinid land crab Discoplax longipes A. Milne-Edwards, 1867, from the western Pacific, can be separated into two distinct groups on the basis of DNA (mitochondrial 16S rDNA and cytochrome oxidase subunit I) and structure of the male first gonopod. On the basis of this data, the material that occurs from the Loyalty Islands to French Polynesia is shown to be D. longipes s. st...
متن کاملTwo New Species of Parathelphusa H. Milne Edwards, 1853, from the Philippines (crustacea: Decapoda: Brachyura: Parathelphusidae)
– Two new species of freshwater crabs in the genus Parathelphusa H. Milne Edwards, 1853, are described from Palawan Island in the Philippines. The new species are each easily distinguished from their closest congeners by characters of the male first pleopod, in conjunction with a unique combination of other morphological characters. A key to the Parathelphusa species of the Philippines is provi...
متن کاملEmbryology of the spider crabs Leurocyclus tuberculosus (H. Milne-Edwards & Lucas 1842) and Libinia spinosa (H. Milne-Edwards 1834) (Brachyura, Majoidea).
The embryonic development of the spider crabs Leurocyclus tuberculosus and Libinia spinosa was divided into five periods based on the differentiation of: (I) cleavage, (II) embryonic primordium, III) optic lobes, (IV) optic lobes pigmented and (V) chromatophores presence. Different traits such as spines, setae and telson morphology distinguish the two species from period III until hatching. Egg...
