Spider, any of more than 46,700 species of arachnids that differ from insects in having eight legs rather than six and in having the body divided into two parts rather than three. It is a common belief of arachnologists and entomologists that the trachea is a new feature that was integrated with genetic adaptation.

Looking at the physiology of respiration the existence of tracheae plays an important role in spiders with a well-developed tracheal system. In: Nentwig W (ed) Ecophysiology of spiders. Some spiders have two sets of book lungs while other spiders have two sets of tracheae.

Spiders are chelicerates and therefore arthropods. Comp Biochem Physiol A-Mol Integr Physiol 159:379–382. However, spiders require less oxygen than people do. One way this is evident is in the way they breathe, and yet can go for hours without breathing at all. And the quiz....!

Being chelicerates, their bodies consist of two tagmata, sets of segments that serve similar functions: the foremost one, called the cephalothorax or prosoma, is a complete fusion of the segments that in an insect would form two separate tagmata, the h… 0000006617 00000 n Each of these organs is located inside an open ventral abdominal, air-filled cavity (atrium) and connects with the surroundings through a small opening for the purpose of respiration. https://doi.org/10.1007/s00360-016-0962-8.

The movement of a spider provides the necessary energy for air to be pushed in and out of the book lungs or trachea.

Most spiders have metabolic rates that are much lower than expected from body mass; but especially those with two pairs of lungs. They are very resilient creatures, so don't underestimate the survival rate of spiders. Air is absorbed through the skin or very small trachea holes located on the underside of the spider's abdomen. It only briefly surfaces to replenish its oxygen supply and occasionally will bring prey to the surface.
