Why Bull Sharks are a Biological Anomaly

It is common knowledge that bull sharks are one of the only species of shark to be able to live in both marine and freshwater ecosystems but sometimes it is taken for granted just how amazing this is. Evolveing to transcend both types of ecosystems is already challenging for bony fish to the point that a fraction of their population have the ability and an even smaller percentage of them can do it freely. Bull sharks are not only abkle to freely travel between salt and freshwater multiple times in their lives but there are specific reasons that make sharks even less adaptable to live in freshwater.
