"Sperm Whales Use Diarrhea Defense to Thwart Orca Attack"
Sperm whales near the Australian coast successfully repelled a pod of orcas by releasing a "cloud of diarrhea," a defensive tactic witnessed by marine biologist Jennah Tucker. Initially mistaking the excretion for blood, Tucker and her team later realized the unusual defense mechanism had deterred the orcas, potentially saving the whales' lives. The incident is rare, as sperm whales are considered apex predators and typically immune to orca attacks.
