This study describes the population abundance and structure of <em>Crocodylus acutus</em> in Palmasola lagoon, Oaxaca. The field works consisted of night surveys during the new moon phase, between the 21:00 and 24:00h. These were conducted during the dry and wet seasons and counted the number of individuals to obtain population estimates. Recorded encounter rates ranged from 32 to 109.3ind./km in 40 journeys deployed with an average time of 18 minutes browsing. The estimated population size using the Messel´s model ranged from 32.7 to 93 individuals. For both seasons, there was a marked dominance of subadults, followed by juveniles and to a lesser extent adult individuals, as well as undetermined individuals (i.e. unknown body/size/length), in both seasons. There was also a significant association with mangrove areas (26.1%) by juveniles; the subadults´s individual use of superficial water (22.7%) and mangrove areas (15.7%); meanwhile the adults were observed on superficial water (9.7%). This information contributes to our understanding of the population ecology of <em>C. acutus</em> in the Palmasola lagoon where the estimated population size seems to show higher values when compared to other reports in the country.</p>}, number={1}, journal={Revista de Biología Tropical}, author={García-Grajales, Jesús and Buenrostro Silva, Alejandra}, year={2014}, month={Mar.}, pages={165–172} }
