The Lapradei Bichir (Polypterus bichir "Lapradei") isn’t your average aquarium fish, it’s a living fossil with style.
These ancient predators date back over 60 million years, and it shows! With their armored, diamond-shaped scales (called "ganoid scales") and fleshy pectoral fins, they look straight out of prehistory.
But the coolest part is their dual breathing system. Bichirs have gills for water breathing and a primitive lung that lets them gulp air from the surface. That means if oxygen gets low, they just take a breath like it’s no big deal. 💨
They even need access to the surface, or they’ll run out of air — talk about being high maintenance! 😆
