Lemon sharks in Brazil just flipped the script—scientists caught them snacking on jaguar cichlids, an invasive fish causing trouble in local waters. Heavy rains connected freshwater to the bay, and the sharks took full advantage. No one’s sure if the cichlids are gone for good or just hiding, but this could be nature’s way of fighting back against invasive species. Who knew sharks could be the unexpected heroes? #Science #naturewin #invasivespecies
