Investigating the Behavioral and Social Context of Sound in the Surface Foraging Strategies of Humpback Whales (megaptera Novaeangliae)
Humpback whales are known for the plastic and variable nature of their acoustic communication, social interactions, and foraging behaviors. Distinct foraging strategies are used to capture different prey types at the surface and on the seafloor. Sounds produced during foraging are thought to facilit...

Humpback whales are known for the plastic and variable nature of their acoustic communication, social interactions, and foraging behaviors. Distinct foraging strategies are used to capture different prey types at the surface and on the seafloor. Sounds produced during foraging are thought to facilitate intraspecific social communication.
