The City of the Dead, or Cairo Necropolis, Egypt.

The people of Cairo call it el’arafa (trans. ‘the cemetery’). It is a 4 mile long dense grid of tomb and mausoleum structures, where some people live and work amongst the dead. Some reside here to be near ancestors, of recent to ancient lineage. Some live here after being forced from central Cairo due to urban renewal demolitions and urbanization pressures.

Here is a Mantis Shrimp. They have some serious business claws.

They strike so rapidly that they generate cavitation bubbles between the appendage and the striking surface. The collapse of these cavitation bubbles produces measurable forces on their prey in addition to the instantaneous forces of 1,500 newtons that are caused by the impact of the appendage against the striking surface, which means that the prey is hit twice by a single strike; first by the claw and then by the collapsing cavitation bubbles that immediately follow. Even if the initial strike misses the prey, the resulting shock wave can be enough to kill or stun the prey.


This is a Rock Hyrax. They’re found in Africa and the Middle East, and their closest living relatives are Elephants & the Sirenia family (Manatees & Dugongs).
