High Quality Content by WIKIPEDIA articles! The Saharan silver ant (Cataglyphis bombycina) is a type of ant that lives in the Sahara Desert. Because of the extremely high temperatures of their environment, and the threat of predators, they are only active a few minutes a day. The twin pressures of predation and temperature restrict the above-ground activity to a narrow temperature band between that at which the predatory lizard ceases activity and the ant's own upper threshold. They often traverse mid-day temperatures upwards of 115°F (46°C) to scavenge the corpses of heat-stricken animals.
