3. Bottlenose Dolphins
In Shark Bay, Australia, bottlenose dolphins exhibit remarkable tool use by employing marine sponges as protective shields for their snouts while foraging along the seafloor. This behavior, known as “sponging,” is predominantly observed in females and is passed down through generations, representing rare evidence of non-primate tool culture.
