Pagurus ikedai (Crustacea: Anomura: Paguridae), a new hermit crab species of the bernhardus group from Japanese waters
A new species of Paguridae, Pagurus ikedai, from the Tokyo Submarine Canyon and vicinity, Japan, is described and fully illustrated, including infoimation on live coloration. This new species is distinguished primarily by size and shape of the chelipeds, in particular the massiveness of the left, and the presence in some males of a papilla or very short sexual tube on the right coxa of the fift...
متن کاملReproductive and larval biology of the sub-Antarctic hermit crab Pagurus comptus reared in the laboratory
Fecundity, hatching rhythm, and the planktotrophic larval development of the hermit crab Pagurus comptus from sub-Antarctic waters of the Beagle Channel (Tierra del Fuego) were studied under controlled laboratory conditions of temperature, light cycle, food supply, and salinity. Fecundity was low, ranging from 134 to 848 eggs per female (cephalotoraxic shield length, SL, 2.3^5.0mm). Hatching ob...
متن کاملTaxonomic re-examination of the hermit crab species Pagurus forceps and Pagurus comptus (Decapoda: Paguridae) by molecular analysis
The current taxonomy of two poorly known hermit crab species Pagurus forceps H. Milne Edwards, 1836 and Pagurus comptus White, 1847 from temperate Pacific and Atlantic coastlines of South America is based only on adult morphology. Past studies have questioned the separation of these two very similar species, which occur sympatrically. We included specimens morphologically assignable to P. force...
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...
متن کاملA remarkable new crab-like hermit crab (Decapoda: Paguridae) from French Polynesia, with comments on carcinization in the Anomura.
Patagurus rex gen. et sp. nov., a deep-water pagurid hermit crab, is described and illustrated based on a single specimen dredged from 400 m off Moorea, Society Islands, French Polynesia. Patagurus is characterized by a subtriangular, vaulted, calcified carapace, with large, wing-like lateral processes, and is closely related to two other atypical pagurid genera, Porcellanopagurus Filhol, 1885 ...
