First Record of Bioacoustic Emission in Embryos and Hatchlings of Hawksbill Sea Turtles (Eretmochelys imbricata) Available to Purchase

Recordings were made in nests of Eretmochelys imbricata and 107 samples of 10-min recordings revealed 575 sounds that were classified manually into 4 categories. Our results show that hawksbill turtles vocalize within the nest, especially during and after eclosion, which suggests vocalizations are important for communication among hatchlings to synchronize emergence from the nest.
