The human body contains many types of cells and a human can be killed by the loss of a single tissue in a vital organ [citation needed]. For many short term radiation deaths (3 days to 30 days) the loss of cells forming blood cells ( bone marrow ) and the cells in the digestive system (wall of the intestines ) cause death.
Researchers matched the post-mortem skin injuries of a human corpse to the mouthparts of such beetles and, in doing so, revealed necrophagous activity in the dermis and epidermis. Notably, the necrophagy elicited by Rhantus validus also created microhabitats for other, smaller necrophages by allowing access to freshly dead internal tissue.
The words: "The most dangerous animal in the world" were printed in red on top of a cage. [6] Behind the bars of the cage, there was a mirror.
