Once the prey is immobilized, the tarantula secretes digestive enzymes that liquefy its body. The spider then sucks up its meal using straw-like mouthparts under its fangs. A tarantula has a "sucking stomach" that enables the ingestion and digestion of liquids.
When the sucking stomach's powerful muscles contract, the stomach inflates, creating a strong suction that permits the tarantula to drain its liquefied prey up through the mouth and into the intestines. Once the liquefied food enters the intestines, it is broken down into particles small enough to pass into the bloodstream through the intestinal walls. The nutrients are spread and absorbed throughout the body in this way. After feeding, the carcass of the prey is formed into a small ball and disposed of by the tarantula.
Tarantulas hunt close to where they live, which is why they can be found preying on organisms in a wide range of habitats. Some genera of tarantulas hunt prey primarily in trees, while others hunt on or near the ground. They may choose where to seek food based on what is available nearby or what type of prey they are after. Silk is very useful in hunting prey for many species of tarantulas.
While all tarantulas can produce silk, it can be used in a variety of ways. Tree-dwelling species typically reside in a silken "tube tent" where they can watch for prey and eat their meals. Terrestrial species line their burrows with silk that stabilizes the burrow walls and enables them to climb up and down when it is time to hunt or mate.
Unlike other spiders, tarantulas do not use their silk to trap or web prey. How They Eat The tarantula approach to eating is a rather fascinating and unconventional one.

Tarantulas live in dry, well-drained soils in open areas throughout the desert and grassland areas. All North American tarantulas are ground-dwellers although some other species live in trees, cliffs, caves, or in crops like bananas and pineapples.
Tarantulas occur worldwide. Those in North America occur in the southern and southwestern states, with many other species occurring to the south throughout Mexico, Central and South America.
Some tarantula species are endangered because of habitat destruction and over-collection for the pet trade. Our local species is common and is not currently threatened.
