Resumen:
All crocodiles studied to date exhibit temperature-dependent sex determination. During the many weeks from
egg laying to hatch there is a period of 10 to 15 d in the middle third of incubation (in the American alligator) during
which the sex of the embryo is irreversibly fixed, referred to as the temperature-sensitive period or TSP. In this work
we investigated the TSP in Caiman latirostris eggs incubated at female-inducing and male-inducing temperatures (29◦C
and 33◦C respectively) by switching eggs from 29◦C to 33◦C and vice versa at timed interval throughout incubation.
Compared to Alligator mississippiensis the duration of TSP was longer, and the onset of TSP was at an earlier stage of
incubation.Caiman latirostris eggs incubated at female-inducing and male-inducing temperatures (29◦C
