British swimmer Rob Howens was in the water with his young daughter off New Zealand's North Island when a pod of dolphins unexpectedly surrounded them. According to witnesses and lifeguards, the dolphins formed a tight circle around them, repeatedly guiding them toward shore. Shortly after, a great white shark, approximately three meters long, was spotted nearby. For about 30 to 40 minutes, the dolphins maintained their formation, using tail slaps and jerky movements to scare the shark away. They only dispersed when the animal swam away, allowing the swimmers to return safely. This encounter is often cited as a powerful example of dolphins' social intelligence and their coordinated protective behavior toward humans.
