Why is the mosquito able to land on water without sinking

Some insects can walk on water due to their weight and the structure of their feet, as well as the surface tension of the water. Because water molecules are more attracted to one other than to other materials, they create a force called surface tension to keep them together.

Explanation: Tiny hairs cover every inch of their legs and make it difficult for water to penetrate. Mosquitoes lack these hairs, but they do have small grooves containing pockets of air covering their legs. The surface tension of water makes it difficult for the water to seep into the grooves, keeping the mosquitoes high and dry

i think its c. amphipod

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
