In February, biologists told us that they had detected signs of a complex culture in cunning yellow-bellied cockatoos, noticed a water bug that walked on the underside of the water surface, and witnessed a previously unseen relationship between wild chimpanzees and gorillas. Of course, there was more news, but we encourage you to read about the most interesting and important ones, which you may have missed. Some animals walk on land, others swim in deep water, and still others walk on water. The latter are able to walk not because of their magical abilities, but because they have attachments that enable them to use the surface tension of the water as a support. A common example of such critters are water bugs. Their body shape allows them to evenly distribute their weight on the water surface in order to avoid sinking, while their leg hairs allow them to easily scuttle around in the water. The more rare variant is shifting not on the top, but on the bottom surface of the water film, that is the road drift. It is attractive, for example, ravelikami, about what you can rozpovisti aquariumisti. It was suggested that some beetles can also do this, but there was no scientific evidence of this until one Australian scientist saw it with his own eyes.
In one of the cauldrons of Australia he remembered a black bug, which seemed to have fallen into the water and hopelessly struggled in it. Having looked closely, he remembered that the mosquito (later it turned out, water lily (Hydrophilidae)) was absolutely comfortable in the water, but what is more important - it was moving down the back, "walking" the lower side of the surface film. We do not know how she managed to do it. However, a small bouillon of wind was remembered on her skull, which could keep the beetle near the water surface. It is also not excluded that the diver had hydrophobic hairs on his legs. Now there are more questions about the extraordinary creature than answers. In particular, it remains unclear why these beetles decided to see and move upside down.
