A Mosquito has 47 teeth.
You may be relieved to know that mosquitoes do not have teeth! But unfortunately, this doesn’t prevent those pesky mosquitoes from biting you.
Mosquitoes have a long tube attached to their mouth, which is designed like a hollow needle called a proboscis. Using their proboscis, mosquitoes are able to pierce your skin and extract your blood, like they were sipping it out of a straw. Consider yourself one, big, mosquito soda fountain!
A mosquito’s proboscis has 47 sharp edges on its tip to help it cut through skin and even protective layers of clothing. Perhaps this is where the rumor of “mosquito teeth” comes from. Unlike human teeth, however, these sharp edges are not used to chew food since blood is already in a liquid form. These sharp edges are simply used to cut through skin. The pain you feel the moment a mosquito “bites” you is therefore not from the mosquito taking an actual bite out of your skin, but instead the pain from the initial stab of sticking its proboscis into you.
