Is a spider's blood transparent?

The spiders have circulating blood in their bodies. The colourless blood, called hemolymph, transports nutrients, hormones, oxygen and cells. The blood also serves another purpose. It is used locally to raise the blood pressure during moulting (shedding of old skin) and stretching the legs.

Do spiders have lungs?

Looking at the physiology of respiration the existence of tracheae plays an important role in spiders with a well-developed tracheal system.

Why is spider blood yellow?

Like human blood, bug blood carries nutrients and hormones to the insect's cells. The greenish or yellowish color of insect blood comes from the pigments of the plants the bug eats.

Do spiders need sperm?

When most spiders mate, the male ejects sperm into the female's genital organs, and the sperm is then stored in a pouch called the spermatheca. She releases the sperm later to fertilize eggs in the uterus—so the last male to mate with her will most likely father her offspring.

Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
