We performed a comparative analysis of fecundity and reproductive effort of two hermit crab species,  Clibanarius antillensis  and  Calcinus tibicen , distributed along the two marine provinces in Brazilian coast. Samples of both species were manually collected during spring low tides on a two-month basis, from February 2011 to January 2012 at locations separated by ~ 3000 km: North-eastern (NE) region – Pedra Rachada Beach (Ceará); South-eastern (SE) region – Araçá Beach and Grande Beach (São Paulo). The size of ovigerous females, as well as the fecundity values, egg volume, internal volume of occupied shells, and reproductive effort were analysed, and the results evidenced significantly higher values for females of both species collected in SE localities. In females collected NE, there was also the presence of aberrant eggs, which influenced the reproductive parameters analysed for these species, resulting in lower reproductive effort. Biomass invested in egg production varied between populations, but ovigerous females of SE invested a higher percentage of their weight in the production of its egg mass, showing significant differences in the reproductive effort. Variation in reproductive performance detected for both species may be related to latitudinal location and associated to the habitat’s characteristics.
