| Abstract |
|
The hatchlings Caretta caretta, during the eclosion and before the abandon of their nest, produce sounds associated to creakling and scrape of the eggshell, and howl, whistle and cough, in a frequency range between 300 and 2600 Hz. Nevertheless, the howls and whistles, that could be associated to a vocalization apparatus, were emitted at a higher frequency (1500-2600 Hz) than the auditory range describe for this species (250-1000 Hz), and therefore probably inaudible for them. However, sounds generated as a consequence of breathing exercises and sand expulsion from the airways through coughs (300- 1200 Hz), by the recently hatched turtles, could be used as signal or stimulus for the hatch of the reminder eggs in the nest.
