چکیده
A Jiew freshwater crab, h'csonna dotpin'tmm sp. ji.h is described from Jamaica. The number of known Jamaican e-jidteinic Sesairriinfle increases thereby tu> eigln. Half of the American species of .Vmnwfl feriown fit present are mct&mic in Jamaica. The new species in locally restricted to the slopes of toe Dolphin Head Mountain in western Jamaica. It jwobahiy evolved when sea-level fllJCHJiiiious during the PI Eocene isolaled this mountain from Central Jamaica. 5esutnta dolptumutn is closely r io ted to St-samta jessamin Schuhartr Reirner, Diesel &.

Ontogeny of osmoregulation and salinity tolerance in a mangrove crab, Sesarma curacaoense (Decapoda: Grapsidae).
The grapsid crab Sesarma curacaoense is believed to represent the closest saltwater relative to the ancestor which gave rise to an adaptive radiation of endemic freshwater and terrestrial species on the island of Jamaica. Living in mangrove swamps with variable salinity conditions and showing semiterrestrial behaviour, S. curacaoense exhibits ecological adaptations to non-marine conditions. In ...
متن کاملThe early life history of Sesarma fossarum, an endemic freshwater crab from Jamaica
The freshwater crab Sesarma fossarum (Decapoda, Brachyura, Sesarmidae) was only recently described as a new species. As in most other endemic Jamaican crabs that have radiated in limnic and terrestrial environments, its early life history has been largely unknown. In an experimental laboratory study this species was reared through embryonic, larval, and early juvenile development, and ontogenet...
متن کاملA molecular method for the detection of sally lightfoot crab larvae (Grapsus grapsus, Brachyura, Grapsidae) in plankton samples
The decapod Grapsus grapsus is commonly found on oceanic islands of the Pacific and Atlantic coasts of the Americas. In this study, a simple, quick and reliable method for detecting its larvae in plankton samples is described, which makes it ideal for large-scale studies of larval dispersal patterns in the species.

Rocky shores are one of the most important habitats of marine environment in coastal areas. This study was done in 2010-2011 to investigate the diversity of true crabs in intertidal rocky shores of Qeshm island. Samples were collected from intertidal zones during the low-tide at 5 stations. The specimens were fixed in 70% Etanol and transferred to laboratory for identification. Altogether, 15 c...
