Close Encounter: Swimmers Brave Stranded Whale at Leighton Beach

Beachgoers at Leighton beach in Perth, Australia, were captured on video swimming alongside a giant sperm whale that had strayed into shallow waters. Marine biologist Dr. Natalie Sinclair warned that the whale's behavior was unusual and perilous, and urged people to leave the whale alone to avoid disorienting it. The whale, which had stranded itself twice in the past two days, may have been looking for a place to rest and could potentially be euthanized if it cannot get off the sandbar. Authorities have also issued a warning to swimmers about the potential presence of sharks attracted by the whale.
