Epaulette Shark Adaptations and Evolution

Scientists in northern Australia discovered the epaulette shark, the youngest shark species at nine million years old. This shark can walk on land using its muscular fins, showcasing unique adaptations. It can survive in hot water and on land by slowing its breathing and heart rate. The epaulette shark's abilities highlight evolutionary processes, similar to how whales evolved from land animals. This discovery suggests that sharks might one day evolve to live on land.
