A total of 223 individuals of C. virgatum and 6 of C. hunteri in 19 clumps were attached to the snake's body. The barnacles ranged in size from 1.4 mm (cypris larvae) to 18.2 mm in capitulum length in C. virgatum, and from 10.7 to 14.4 mm in C. hunteri. The size of the smallest gravid individuals in both species was between 10 and 11 mm. The distribution of C. virgatum on the snake was non-random both longitudinally and dorso-ventrally, with more barnacles in the posterior region and on the ventral side of the snake, respectively. The proportion of gravid individuals increased towards the tail. -

The Malacostracan Fauna of Two Arctic Fjords (West Spitsbergen): the Diversity And

The material was collected during 12 summer expeditions organized from Diversity; 1997 to 2013. In all, 24 pelagic and 116 benthic taxa were recorded, most of them widely Distribution distributed Arctic-boreal species. The advection of different water masses from the shelf had a direct impact on the structure of the pelagic Malacostraca communities, resulting in the clear dominance of the sub-arctic hyperiid amphipod Themisto abyssorum in Kongsfjorden and the great abundance of Decapoda larvae in Hornsund. The taxonomic, functional and size compositions of the benthic malacostracan assemblages varied between the two fjords, and also between the glacier-proximate inner bays and the main fjord basins, as a result of the varying dominance patterns of the same assemblage of species. There was a significant drop in species richness in the strongly disturbed glacial bays of both fjords, but only in Hornsund was this accompanied by a significant decrease in density and diversity, probably due to greater isolation and poorer quality of sediment organic matter in its innermost basin. -

F. Davie Queensland Museum, PO Box 3300, South Brisbane, Queensland, Australia Email: [email protected] ABSTRACT. – An annotated checklist of the extant brachyuran crabs of the world is presented for the first time. Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Lebbeus laurentae is fully redescribed because the original and subsequent descriptions are not totally detailed. Differentiating characters among the three new species and close allies are discussed. Previous records of Leb- beus species from hydrothermal vents are reviewed.

Native Decapoda
NATIVE DECAPODA Dungeness crab - Metacarcinus magister DESCRIPTION This crab has white-tipped pinchers on the claws, and the top edges and upper pincers are sawtoothed with dozens of teeth along each edge. The last three joints of the last pair of walking legs have a comb-like fringe of hair on the lower edge. Also the tip of the last segment of the tail flap is rounded as compared to the pointed last segment of many other crabs. RANGE Alaska's Aleutian Islands south to Pt Conception in California SIZE Carapace width to 25 cm (9 inches), but typically less than 20 cm STATUS Native; see the full record at http://www.dfg.ca.gov/marine/dungeness_crab.asp COLOR Light reddish brown on the back, with a purplish wash anteriorly in some specimens. Underside whitish to light orange. HABITAT Rock, sand and eelgrass TIDAL HEIGHT Subtidal to offshore SALINITY Normal range 10–32ppt; 15ppt optimum for hatching TEMPERATURE Normally found from 3–19°C SIMILAR SPECIES Unlike the green crab, it has 10 spines on either side of the eye sockets and grows much larger. It can be distinguished from Metacarcinus gracilis which also has white claws, by the carapace being widest at the 10th tooth vs the 9th in M. gracilis . Unlike the red rock crab it has a tooth on the dorsal margin of its white tipped claw (this and other similar Cancer crabs have black tipped claws). ©Aaron Baldwin © bioweb.uwlax.edu red rock crab - note black tipped claws Plate Watch Monitoring Program . -
