Dioecy. Gonochorism. Hermaphrodite. v. t. e. Temperature-dependent sex determination (TSD) is a type of environmental sex determination in which the temperatures experienced during embryonic/larval development determine the sex of the offspring. [1] It is observed in reptiles and teleost fish, with some reports of it occurring in species of ...
The caiman does not have sex chromosomes, but instead depends on temperature to determine the ratio of male and female offspring. Eggs at warmer temperatures (32 °C (90 °F) or higher) develop into males and eggs at cooler temperatures (31 °C (88 °F) or lower) develop into females. [ 18 ]

The largest female on record measured about 4.3 m (14 ft 1 in) in total length. [39] Female are thus similar in size to other species of large crocodiles and average slightly smaller than females of some other species, like the Nile crocodile. [37]
