Even with this, humans have normally experienced a fascination with crocodiles. Even courting again to historic Egyptian periods, folks worshiped a crocodile god named Sobek. You will discover even paintings that depict this god being used in spiritual ceremonies.
Whilst intraspecific interaction among copyright of precisely the same species is available in handy for defending territory, it’s also useful On the subject of communal nesting. It lets the women to establish some kind of composition inside the place and stops conflict.
Western Africa It is just a heavily armoured species with uniform black coloration in Older people, even though juveniles Possess a lighter brown banding.
