Keys to the Identification of Brachyuran Larvae of the Black Sea

Abstract

The Black Sea fauna has been studied for a long time, whence the adult crabs of this region are rather well known. However, not enough attention has been paid to their larval development. Despite the extensive literature concerning the order Decapoda pertaining to the Black Sea, there is no key for the identi cation of the brachyuran larvae. This work aims to ll that gap.There are 20 species of crabs in the Black Sea, belonging to 7 families: Cancridae with 1 species: Cancer pagurus L., 1758; Pirimelidae with 2 spp.; Portunidae (6 spp.); Xanthidae (4 spp.); Grapsidae (3 spp.; the presence of Planes minutus (L., 1758) for the Black Sea is not con rmed, therefore this species has not been included in the key); Majidae (3 spp.); and Potamidae (1 sp.).

Oceanographic mechanisms that possibly explain dominance of neritic tropical zooplankton species assemblages around the Islas Marias Archipelago, Mexico

“…Twelve zooplankton taxonomic groups were identified at the species level using as principal sources, but not exclusively, standard taxonomic keys for Copepoda (Palomares-García et al, 1998;Razouls et al, 2005Razouls et al, -2012, http://copepodes.obs-banyuls.fr/en/), Euphausiacea (Baker et al, 1990;Brinton et al, 2000), Mysidacea (Tattersall, 1951;Ii, 1964;Mauchline, 1980;Harrison & Bowman, 1987;Deprez et al, 2005; NeMys webpage http://nemys.ugent.be/; Murano & Fukuoka, 2008), Decapoda (Williamson, 1957a(Williamson, , 1957b(Williamson, , 1960(Williamson, , 1962(Williamson, , 1967(Williamson, , 1983MacDonald et al, 1957;Pike & Williamson, 1972;Fichman & Williamson, 1978;Albornoz & Wertmann, 1997;Anosov, 2000;Dos Santos & Lindley, 2001;Puls, 2001;Dos Santos & González-Gordillo, 2004), Chaetognatha (Alvariño, 1963(Alvariño, , 1967Casanova, 1999), Pteropoda (Seapy, 1990;Spoel, 1996;Spoel et al, 1997;Angulo-Campillo, 2009), Hyperiid amphipods (Vinogradov et al, 1996;Zeidler, 2006), and ichthyoplankton (Brogan, 1992;Moser, 1996;Beltran-León & Rios-Herrera, 2000). A relative large proportion of specimens, particularly fish and decapod larvae, were not identified to species, because their larvae have not been described yet.…”

Morphological differentiation of megalopae in the family Panopeidae Ortmann, 1893, from a lagoon system inlet in the southwestern Gulf of Mexico

“…Considering the characteristics described above and the criteria proposed by Anosov (2000) to distinguish between families, a key for the identification of megalopae of the species of the family Panopeidae here studied was constructed. An additional key differentiates the Panopeidae from the other brachyuran families found in the area.…”
