Thus, the impala has once again turned to its external anatomy in order to make life more manageable. To put it basically this digestive system allows the animal to seek shade far more often than their hindgut fermenter competition, because it is just astoundingly more efficient, which means they have more time to relax during the hottest hours of the day.Īfrica is still a hot place though, whether you are in the shade or not, and even when you have a very efficient digestive system you still need to contend with the sun. This digestive system is call “rumination”, which you may remember from one of my previous Safari Science videos. For one, they have a completely different digestive system to elephant and zebra. However, they have developed a rather ingenious way to fight off the African sun. One doesn’t actually consider very often how any animal keeps cool, let alone the impala.

In turn, this means we often just drive right past them in search of the more elusive species, but they are actually very interesting animals that I feel need a bit of limelight. Estimations put them at about 120 000 in the Greater Kruger National Park alone! What this means, is that people get to see them, and people see them a lot. When I said earlier that they occur in incredible numbers, I really meant it. However, this is a subject for another day all together. Sadly, they feed on grass and so they need to spend most of those feeding hours in the direct sunlight.

Well they do, but because their digestive system is fairly rudimentary and inefficient, it means they need to spend most of their day feeding. Many of you may be wondering why zebra don’t just head for shade during the hottest parts of the day. This is basically a very small flow of wind that spurs on the evaporative cooling affect of sweating to a much greater effect. You see, as the black stripes get warmer than the white stripes (and they can be by several degrees) a minute convection current begins to form as the warm air coming off the black stripes becomes attracted to the cooler air coming off the white stripes. And it is this sweat along with the difference in stripe temperature that add up to a remarkable cooling affect. However, what few people do not always realise is that zebra, like horses, sweat. Now we all know that black attracts heat and white repulses it, but zebra are probably pretty evenly black and white and so, this would defeat the point.
