Spermatophore transfer in the hermit crab Clibanarius vittatus (Crustacea, Anomura, Diogenidae).
Although mating has been described in several hermit crab species, the mechanics of spermatophore transfer have not previously been demonstrated. Evidence from pleopod and gonopore morphology, video observations, and inseminated females indicates that in Clibanarius vittatus the male applies a spermatophoric mass directly onto the female via the gonopores rather than with modified pleopods 1-2 ...
متن کاملIntraspecific variation in vertical habitat use by tiger sharks (Galeocerdo cuvier) in the western North Atlantic
Tiger sharks (Galeocerdo cuvier) are a wide ranging, potentially keystone predator species that display a variety of horizontal movement patterns, making use of coastal and pelagic waters. Far less, however, is known about their vertical movements and use of the water column. We used pop-up satellite archival tags with two data sampling rates (high rate and standard rate tags) to investigate th...
متن کاملIntraspecific Variation in Carapace Morphology Among Fiddler Crabs (Genus Uca) From the Atlantic Coast of Brazil
Isolation due to geographical barriers should promote genetic and morphological divergence among populations. Marine currents flowing in opposing directions along landmasses can constitute barriers that isolate populations dependent upon aquatic dispersal. The distribution of fiddler crabs (genus Uca) is regulated primarily by the oceanic transport of their planktonic larvae and by available ad...
متن کاملPagurus Asper H. Milne Edwards, 1848, a subjective synonym of Clibanarius longitarsus (De Haan, 1849) and reversal of precedence (Crustacea: Decapoda: Anomura: Diogenidae).
The species-group name Pagurus longitarsus was proposed by De Haan (1849: 211, pl. 50, fig. 3) for a species of hermit crab collected from Japan (see Yamaguchi & Baba 1993: 272, 273). Dana (1852b: 464) transferred Pagurus longitarsus to the genus Clibanarius Dana, 1852 (first established in Dana 1852a). Dana (1852b: 464) also suggested that Pagurus longitarsus De Haan, 1849, and Pagurus asper H...
متن کاملShell occupation by the endemic western Atlantic hermit crab Isocheles sawayai (Diogenidae) from Caraguatatuba, Brazil.
The aim of this study was to characterize the pattern of shell occupation by the hermit crab Isocheles sawayai Forest and Saint-Laurent, 1968, from the Caraguatatuba region. The percentage of shell types that were occupied and the morphometric relationships between hermit crabs and occupied shells were analyzed from systematized collections that were conducted monthly from July 2001 to June 200...
