This study explored the population biology and reproduction of Tozeuma carolinense in Laguna de Términos, Campeche, southwestern Gulf of Mexico, collected bimonthly from June 2009 to June 2010. The sample of 2,109
specimens analysed had a sex ratio of 0.39 males per female. On average, females were significantly larger (6.16 ± 2.02 mm carapace length, CL) than males (4.42 ± 0.70 mm CL). Recruitment was continuous, with the highest
percentages of juveniles during June 2009 and June 2010. The estimated asymptotic length with the von Bertalanffy model was 10.13 mm CL for females and 6.62 mm CL for males. Longevity was 6 months for females and 5 months
for males, with males having a higher mortality (Z = 1.08) than females (Z = 0.85). The reproduction was continuous, with highest incidence of berried specimens from August 2009 to April 2010. The estimated size at sexual maturity for females was 6.67 ± 1.30 mm CL. There was a significant correlation between female size and the number of embryos, with a mean fecundity of 268 ± 131 embryos. During the incubation period females lost 46% of the embryos.
