Digestion is carried out internally and externally. Spiders secrete digestive fluids into their prey from a series of ducts in their chelicerae (fangs). These digestive fluids dissolve the prey's internal tissues, then the spider feeds by sucking the partially digested fluids out. Spiders consume only liquid foods. Many spiders will store prey temporarily. Web weaving spiders that make a shroud of silk to quiet their envenomed prey's death struggles (such as Redbacks) will generally leave them in these shrouds to be consumed at their leisure.

Despite its taxonomic classification as a carnivore, the panda has a diet that is primarily herbivorous, which consists almost exclusively of bamboo. However, pandas still have the digestive system of a carnivore and do not have the ability to digest cellulose efficiently, and thus derive little energy and little protein from consumption of bamboo. The average Giant Panda eats as much as 9 to 14 kg (20 to 30 pounds) of bamboo shoots a day.
