Spiders cannot chew their prey because they do not have teeth. Instead, they inject stomach juices into their paralyzed prey with dissolves them, and then suck the liquid out.

How do spiders eat if they cannot chew?

As far as I know, the answer to this question depends on the type of spider you are referring to. Some spiders can eat solids. So, they simply bite and chew. While other spiders can not eat solids. These spiders will inject their prey with venom, and the venom liquefies the insect's insides. The spider will then essentially "drink" it's food.


How do black widow spiders eat there food?

Like many other spiders, the jaw parts of black widow spiders are too small and delicate to chew up their prey. So these spiders pump digestive juices into the bodies of their prey. After a while, the digestive fluids will have liquified all the digestible content inside the prey's exoskelaton, and then the spider sucks the fluid back into its own body. Some other kinds of spiders have more robust chelicerae (the parts that are terminated by the fangs), and they have tooth-like protrusions on them. These spiders use their chelicerae to chew up the bodies of prey, adding digestive juices in the process, and so they are able to get nutrition from parts of the prey bodies that black widows can't get at.

Do Spiders and Grasshoppers have chewing teeth?

Many people are not aware that the order Araneae (spiders) is one of the most diverse orders in the animal kingdom. Different spiders catch and eat their prey in a variety of ways. Spiders in the family Agelenidae, for example Tegenaria agrestis (hobo spiders) do actually have teeth, and chew their food. Many families of spiders inject their digestive juices into their prey. These spiders must first chew a small hole into the prey. They have specialized stomach pumps to suck the prey dry. Spiders in the family Theridiidae, such as Lactrodectus sp. (black widows) are an example of this type of spider. It is important to note that depending on how the spider feeds, it will leave behind different types of bug corpses. A hobo spider for instance will leave behind a very small ball of what is left that was too tough to chew and digest. Sometimes they will leave behind nothing! Black widows will leave behind a fully intact exoskeleton as they only suck out the inside of prey. They will drop this to the bottom of their web when done eating.


What do spiders eat and how do they catch there prey?

Spiders eat other insects. Most spiders build webs that have sticky strands to trap small insects who get tangled up when they fly into it. When the spider feels something struggling in its web it will run over and bite the prey, which will paralyze it and turn its insides to liquid (spiders can't chew). The spider then wraps its prey up in silk (like a mummy!) and it waits until the prey's insides turn to liquid so it can drink it up. Yum! Try watching a spider eat a fly from a web at home.

Yes, spiders possess venom, not poison. They use their venom to immobilize and digest their prey. Spiders inject venom into their prey through their fangs, which helps them catch and consume their food.
