Have you ever heard the tale of the African crocodile and the Egyptian plover?
The story of these two species and their symbiotic relationship has been around for thousands of years. Here, both the crocodile and plover benefit from the actions of the other. Its completely mutual.
According to this myth (and loosely based facts), the crocodiles lie on the shores of the Nile River with their mouths open while plover fly into the open mouths and, like a giant piece of dental floss, eat the leftover meat stuck between the crocodile’s teeth. The plover get full and the crocodiles keep their bright smiles.
The validity of this relationship is constantly in question — in fact most believe it is a myth — but it teaches an important concept of nature where two seemingly different parts can work together for the overall good.
