Monkeys are adaptable mortals, and none more so that those living on remote islands in the eastern Indian Ocean. Employing an array of implements to get meat, it is about to change that they too take good care of their teeth, even going so far as to floss them with feathers.
New research is molting light on the impressive display of implement call shown by troops of Nicobar long-tailed macaques, a subspecies are restricted to precisely three islands in the Andaman and Nicobar archipelago off the eastern coast of Myanmar. It seems these isolated primates have come up with a whole repertoire of ingenious ways and means to get more nutrient, and also to improve on the mint they’ve already got.
Publishing their results in the gazette Primates, researchers have recorded the varied channels in which the apes live on small island developing. They macaques have become particularly good at obtaining coconuts, climbing trees and twisting the drupes before nibbling the stalk with their teeth. If the coconut is young enough, they’ll withdraw existing straw with their teeth, but if it is more mature, they have taken to pounding the food on stones and concrete in order to get to the deliciou flesh and water inside.
But sometimes the meat you already have is not quite edible, and the monkeys have this covered very. For harmful cashew seeds, the macaques scratch the surface with whatever is lying around, be it dry leaves, plastic, or scum from humen. They have also been found to brushing meat that is covered in sand, while others were observed utilizing puddles to cleanse return.
To round stuffs off, the primates were found to have amazingly good dental cleanlines. After chowing down on a meal, the apes would use a variety of fibers to floss their teeth. By supporting the fibers between their teeth and gathering on them, use whatever they had to side such as a bird’s feather, a piece of coconut husk, or a piece of nylon, they were able to do a apparently good job at scavenging their gnashers. The monkeys were even found to modify the fiber if it was too thick.
This is not the first time that people of our primate cousins have been discovered impeding their teeth in good nick. Japanese macaques have been identified applying their own wool to floss, while a group of long-tailed macaques living near a Buddhist shrine in Thailand has been experienced( quite creepily) to use human fuzz to floss, with mothers even learning their offspring the perfect technique.
None of these actions are necessarily unique to the Nicobar long-tailed macaques, though one does stand out, in which the apes purposefully shake floras and thickets to ruffle insects that they then catch and gobble down.
