Top 10 Prehistoric Fish Alive Today_polypterus Senegalus

These african fish are often called dinosaur eels, due to their reptilian appearance and serrated dorsal fin, reminiscent of some dinosaurs spiked backs. They are not really eels, but members of the bichir family. Bichirs were already around in the Cretaceous, so the dinosaur part of their name is actually fitting in a way. Although often sold as exotic pets, dinosaur eels are prone to escaping their fish tanks. They can survive out of the water for long periods of time as long as their skin remains wet, which enables them to wander far away from their tank.
