 | | They get their name not from their skin color, which tends to be olive to gray, but rather from the blue-fl color of the inside of their mouth, which they display when threatened. |
 | | Before the advent of fl mamba antivenin, a bite from this fearsome serpent was 100 percent fatal, usually within about 20 minutes. |
 | | Unfortunately, antivenin is still not widely available in the rural parts of the mamba’s range, and mamba-related deaths remain frequent. |
