Abstract

A total samples of 858 of Cardisoma armatum and Cardisoma guanhumi) collected from the Lagos Lagoon mangrove area of the University of Lagos were studied for their frequency, distribution, growth and sex ratio and a comparative analysis was done on both crabs. Investigation into their length-weight relationships, growth pattern, condition factor, food and feeding habits were carried out. The calculated Chi-square ( 2Ù„ا ) test showed that male crabs of Cardisoma armatum and Cardisoma guanhumi were significantly (p<0.05) more abundant than the female crabs. The Condition factor K values for the Cardiosoma armatum and Cardiosoma guanhumi ranged from 3.3 to 30.7 and 3.1 to 28.6, respectively. This research study indicates almost similar biological features for both species.
