Shell Exchange in Hawaiian Hermit Crabs
Shell exchange behavior of intertidal Hawaiian hermit crabs was observed in the laboratory. Outcomes of 255 shell-related interactions were analyzed to test the predictive powers of two models of resource exchange . In the case of intraspecific interactions, the negotiations model (which predicts that exchanges should occur only when both crabs will gain in shell value) was superior to an aggre...
متن کاملMorphometric Relationships Between the Hermit Crab Isocheles sawayai (Forest & Saint Laurent) (Crustacea Anomura Diogenidae) and its Shell from Southern Brazil
A study on morphometric relationships between the hermit crab Isocheles sawayai and its shell in a population from Paraná-Santa Catarina States coast was carried out. Hermit crabs from the by-catch of shrimp fishing (4-15m depth) were collected. Cephalothoracic shield length (CL) and width (CW) from hermit crabs and total length (SL), aperture length (AL) and weight (SW) from shells were taken....
متن کاملA new species of the hermit crab genus Diogenes (Crustacea: Decapoda: Anomura: Diogenidae) from southern India.
A new species of the hermit crab genus Diogenes Dana, 1851 (Diogenidae), D. canaliculatus, is described and illustrated on the basis of material from off the Kerala State, southern India. It is referred to the D. edwardsii (De Haan, 1849) species group, and compared with D. bicristimanus Alcock, 1905, D. fasciatus Rahayu & Forest, 1995, D. laevicarpus Rahayu, 1996 and D. moosai Rahayu & Forest,...
متن کاملSpermatophore 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 کاملDramatic mitochondrial gene rearrangements in the hermit crab Pagurus longicarpus (Crustacea, anomura).
The entire mitochondrial gene order of the crustacean Pagurus longicarpus was determined by sequencing all but approximately 300 bp of the mitochondrial genome. We report the first major gene rearrangements found in the clade including Crustacea and Insecta. At least eight mitochondrial gene rearrangements have dramatically altered the gene order of the hermit crab P. longicarpus relative to th...
