The Nile crocodile (Crocodylus niloticus) is an African crocodile widespread throughout Sub-Saharan Africa, occurring mostly in the central, eastern, and southern regions of the continent and lives in different types of aquatic environments such as lakes, rivers and marshlands.
The spur-winged lapwing or spur-winged plover (Vanellus spinosus) is a lapwing species, one of a group of largish waders in the family Charadriidae. It is one of several species of wader supposed to be the "trochilus" bird said by Herodotus to have been involved in an unattested cleaning symbiosis with the Nile crocodile.
The Egyptian plover (Pluvianus aegyptius), also known as the crocodile bird, is a wader of the family Pluvianidae. The species is one of several plovers doubtfully associated with the "trochilus" bird mentioned in a supposed cleaning symbiosis with the Nile crocodile.
