Did you know some Aussie dolphins are basically DIY tool users? They wear sponges on their noses to hunt for hidden fish—like little sea detectives! It protects their beaks but messes with their echolocation, so only a few dolphins (taught by their moms!) actually master it. Scientists found they have to rewire their brains to make it work. Wild, right? Only about 30 dolphins in Shark Bay have this quirky skill! #Science #Dolphins #AnimalBehavior
