Aphids are also capable of diving like humans

In order to stabilize the underwater posture, divers often wear a inflatable jacket or be slightly deflated. The aphid species ( Anisops deanei ) specializing in backyard swimming also applies the same system.

According to researchers Philip Matthews and Roger Seymour of the University of Adelaide (Australia) in Nature, aphids pump a gas in the surface before diving and adjusting the volume of the gas to keep it private. underwater

Researchers say other water insects use gas to scuba dive. These puffles act as carriers of water-soluble oxygen recovery fish so their diving ability is limited. They often float on the surface or cling to underwater objects.

The aphid is more favorable than oxygen transporter by hemoglobin - as well as divers. When placing aphids on an extremely sensitive electronic scale, the researchers measured pressure changes in its gas puff. They concluded that the aphid water bug in the gas bubble when diving under water. Their hemoglobin is saturated with oxygen. Once in the water, aphids recover the oxygen needed to be raised in the middle and keep their balance.
