Sexual dimorphism can be seen in these turtles, with adult females being larger on average (average carapace length of 287 mm) than adult males (average carapace length 223 mm). Additionally, the shells of male river cooters are flatter than that of females. Males also possess elongated fore claws as compared to females.
Sexual Dimorphism; female larger; sexes shaped differently; Range length 89 to 274 mm 3.50 to 10.79 in; Development. Texas river cooters rely on temperatures in the nest for sex determination. Males are produced in colder nest temperatures while females are produced in warmer nests. Nests with a temperature between 21.5°C and 27°C ...
Sexual Dimorphism: This species is sexually dimorphic. Adult males averaged 252.3 ± 18.1 mm CL (220-289, n = 19), 225.3 ± 16.2 mm PL (190- 256, n = 19), and 1,563.8 ± 335.0 g body mass (1,066-2,371, n = 19).
6 de jul. de 2023 · We found strong evidence for sexual dimorphism among the species/subspecies, with females larger than males, similar to past studies. Sexual dimorphism was the most extreme in P. c. suwanniensis, with the L ∞ of females 1.36 times greater than that of males, which is similar but lower than the Jackson estimate of 1.5 times
In order to compare the degree of sexual size di-morphism of adult P. concinna between river systems, we used a sexual dimorphism index (SDI) proposed by Gibbons and Lovich (1990), where SDI = x CL of adults of the larger sex/ x CL of adults of the smaller sex. We compared mean carapace length of adults of each sex between river systems using t ...
Fiddler crabs are sexually dimorphic, meaning that they exhibit characteristics that distinguish males and females. Here, both males and females possess front claws, but in males, the size of one claw is enlarged. The male’s large claw is the result of sexual selection, as males must compete for and be chosen by females for mating .
