Mosquito teeth


I read somewhere that mosquitoes have teeth. Having conducted minimal research, to find out whether they really do, I have a whole new level of revulsion for mosquitoes.

"Mosquitoes have four knife-like tools of serrated teeth that surround a pair of fine tubes — one for dripping a pain suppressor and one for sucking blood.

A common house mosquito (Culex sp.) stabs the skin with her sharp snout and saws in with her four knife tools to draw blood. She shoots in saliva laced with anesthetic (to escape notice) and an anticoagulant (to keep blood flowing). Then she sucks blood.

In 90 seconds, she sucks enough blood to nourish 100 eggs or more — and is too heavy to fly. She makes a controlled descent to a close safe spot where she squeezes in on her abdomen. Water oozes out of the blood, filtered through the abdominal wall, and forms a large drop. Light again, she takes off.

During her short adult life (two weeks to a month) she bites one to three times... only female mosquitoes draw blood (for needed protein). The males feed on nectar and plant juices." Source

Sometimes knowledge is power. Sometimes it's just gross.
