Croatia’s Kornati National Park just got a new (and dangerous) visitor: venomous lionfish! These spiky invaders have no natural predators here and are snacking on native fish, throwing the ecosystem out of whack. Park officials are warning everyone to watch out—those spines can cause some serious pain. If you spot one, report it! Locals are even encouraged to eat them to help control the population. Wild, right? Nature’s balance is at stake! #Pets #lionfish #invasivespecies
