Nile crocodile (Crocodylus niloticus)
Unlike most other crocodilians, female Nile crocodiles will bury their eggs in sand rather than incubate them in rotting vegetation. After burying the eggs, the female then guards them for the 3 month incubation period. The father-to-be will often stay nearby, and both parents will fiercely attack anything that approaches their eggs.
Exactly like here - where the female crocodile - and expectant mother, was trying to eat the photographer in one bite.
