It's high risk in this shallow water, India could easily strand 1.
"I saw India catch a big one and he's a good hunter."
Everything the Beachies do is recorded in minute detail. Across Shark Bay, Janet's research team follow different families of dolphins. She's found a base of females living in very specific areas and each has adapted how they hunt to best exploit their environment. Off the rocky shores to the north, live the surfer moms who've gone to even greater extremes than the Beachies, chasing their prey 2 right onto the breach 3. To the south in the deep channels, there are dolphins that show just how intelligent they are by using tools. The females here wear sponges on their beaks 4. It's thought they use them to protect themselves while feeling around for food on the seabed. They're the only dolphins ever recorded using tools.
Shark Bay is the only place in the world where dolphins hunt in such diverse and unique ways. Fishing over, the Beachies family reunite.
"Hi, guys."
India must soon leave the Beachies. When he does, he will spend a life-time roaming the Bay with other males, becoming a much more generalist hunter.
