science ๐ฌ Dolphins use shells to hunt fish off Australia coast
Marine biologists documented Indo-Pacific bottlenose dolphins using large sea shells to catch fish off Queensland, Australia. This rare 'shelling' behavior was recorded in Hervey Bay, part of the Great Sandy Marine Park, on January 4, 2019. Researchers noted two events in 2025, with a mother teaching her calf the tactic. This suggests vertical social transmission of the skill, challenging current beliefs about dolphin learning. The findings were published on August 8, 2026. ๐ฌ
