An organism that exhibits a head with sensory equipment and a brain probably also have receptors, which capture the stimuli of the environment and transform them into a nervous impulse, and organs of the senses that are the communication channels we have with the environment and thanks to them we understand and interpret the environment, they are: vision, hearing, smell, taste, and touch.
Insects, such as water striders, and spiders, such as fisher spiders, can glide or scamper across the surface of water. These critters are small enough that their weight can be supported almost entirely by surface tension, the relatively weak forces that hold water molecules together.
Surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. ... it also helps water to move up the xylem tissue of higher plants without breaking up
The force pushing against an area or surface
