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 ( χ 2) 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.
