Structure and Function of the Digestive Tract

Chapter

Abstract

Spiders are extraordinary in their mode of digestion which is known as extra-oral. Digestive fluid is poured over and into the prey and the dissolved material is swallowed into the intestine where it is subjected to further and final digestion. Together with this peculiar method of food consumption, we find a number of anatomical adaptations and physiological adjustments, the functional relationship of which has been studied since the early works of Bertkau (1885).
