Petrolisthes laevigatus is commonly found in the intertidal zone from southern Peru to southern Chile. Water loss in the most terrestrial species of crabs was several times greater than terrestrial vertebrates, insects and arachnids and indirect evidence indicates that most water loss of crabs is through the integument exclusive of the gill chamber. Low levels of some nutrients has made them susceptible to anthropogenic effects for linking to Intertidal reef with the most diverse communities have a range of stable habitats with sand. In this study, we determined light perception capability in juveniles and sub-adults of L. vannamei by means of electroretinogram (ERG) measurements. L Gregory, M Campbell, C Primo, C Hewitt (2012), Vol. MeSH Grant and McDonald (1979) and Garces (1987) estimated total percent water lost at death for E. depressus to be 30% on average, less than that measured for an intertidal hermit crab with 50% but greater than that measured for the porcelain crab Petrolisthes elongatus (Milne Edwards, 1837) with 20% (Jones and Greenwood, 1982).
