Hervey Bay sits on the Fraser Coast of Queensland, Australia, a coastal city known for its calm, bay-facing waters and as a hub for tourism and whale watching.
Dolphins off Australia’s east coast are using empty shells to trap prey, a behavior called shelling. The approach has been observed in Hervey Bay and Queensland’s Great Sandy Marine Park, with footage suggesting maternal transmission. Researchers say this adds to evidence of tool use in dolphins and may illuminate how humans evolved tool use.
