Source publication
The genus Sesarma has 18 valid, extant species that are distinguished by the presence of a carina on the back of the chelae. Sesarma aequatoriale had not been reported since 1992 in Ecuador. However, specimens of this species have been observed in an estuarine area using the burrows of the red mangrove crab Ucides occidentalis, generating a hypothe...

... diagnostica más distintiva es la presencia de dos dientes antero-laterales detrás de la órbita vs. tres en S. sulcatum, la especie del género más parecida en el área. Los especímenes estudiados presentan también la región frontal del caparazón levemente cóncavo, la región dorsal con surcos débiles y con penachos de setas muy dispersos (Fig. 2). También, el gonópodo 1 de los machos es menos robusto y con la porción distal proporcionalmente más larga. Estas características coinciden con lo observado por . Por lo tanto, tenemos el segundo registro de S. aequatoriale en Ecuador lo que indica que esta especie es más común en esta parte del ...

The management of invasive species is a current challenge for the conservation of biodiversity. One approach is their utilization as a food source. In this study, 2040 French people were interviewed to assess crustacean consumers’ receptivity to this new species and its desirability as a food. The crab’s appearance (shape and color) had no effect o...
Global temperatures are rising across marine ecosystems in response to climate change. Marine and estuarine-dependent species including the blue crab, Callinectes sapidus, may adapt to warming temperatures phenologically, by shifting the seasonal timing of biological events, such as reproduction. In Chesapeake Bay, average water temperatures have r...
