The hotter the weather, what climbs higher?

The hotter the weather, the higher the temperature and the higher the climb. It's about spiders.

Spiders are members of arthropods. Their bodies are divided into three parts: head, chest and abdomen, and they have eight legs. In summer, due to the rising temperature, many other creatures will hide in the shade to escape the heat, but spiders are not. They will build a web on branches, corners and other high places, and then wait for their prey on the internet.

Spiders have many tiny bristles, which can help them dissipate heat and prevent overheating. At the same time, they also have tiny sweat glands on their legs, which can reduce their body temperature by sweating. In addition, spiders can adjust their body temperature by changing the color and shape of their bodies. When they feel hot, they will choose to hide in the shade or near the water source to cool down.

Morphological characteristics of spiders

Different kinds of spiders vary in length from 0.05 mm to 60 mm. The body is divided into chest and abdomen. Some species have breastplates at the back of the head and chest, and there are usually 8 single pieces at the front end of the head and chest, arranged in two to four rows. There is a big chest plate on the ventral surface, and a lower lip between the two frontal lobes in front of the chest plate. The abdomen is not segmented, and the abdominal stalk evolved from 1 abdominal segment. The abdomen is mostly round or oval, and some have various strange-shaped protrusions.

The ventral rotator evolved from appendages, and there are 8 primitive species, which are located slightly in the front; Most species have six spinnerets, which are located in front of the anus at the back of the body; Some species have four spinnerets, and there are many spinning tubes on the spinneret, which are connected with various silk glands, and the silk is spun from the spinning tubes. Sensory organs include eyes, various sensory hairs, auditory hairs, lyre and tarsal bones.
