Vocalization behaviors in captive bottlenose dolphins (Tursiops truncatus) and rough-toothed dolphins (Steno bredanensis).

ABSTRACT: Odontocetes rely on vocalizations for navigation, foraging, and communication. Their vocalization patterns are associated with environmental conditions and behavioral contexts, particularly in captive populations. This study investigated the vocalization behaviors of captive bottlenose dolphins (Tursiops truncatus) and rough-toothed dolphins (Steno bredanensis) using continuous acoustic monitoring. The focus was on their responses to human-involved training and feeding activities. Comparative analyses revealed that rough-toothed dolphins produced significantly more clicks and fewer whistles than bottlenose dolphins (p < 0.05). During training, bottlenose dolphins reduced their click rate by 41% but increased whistle production by 125%. In contrast, rough-toothed dolphins showed no signific
