A spider uses its chelicerae to catch its prey by stabbing it and injecting venom into it.
The prey is captured by the pedipalps and the sting is inserted in it, the paralyzed or killed prey is sucked using the chelicerae.
Based on your description, it sounds like you might have a species of jumping spider, possibly a bold jumper (Phidippus audax). These spiders are common in North America and are known for their black coloration with distinctive markings like yellow dots and colorful chelicerae (fangs). Jumping spiders are active hunters and are not considered dangerous to humans.
I believe it is a Jumping Spider (Family Salticidae). I just saw one on my porch and looked it up. I found a good picture on www.whatsthatbug.com/spiders4.html. I think I found an even closer likeness here: http://www.dec.ny.gov/docs/wildlife_pdf/common_spiders.pdf
copied answer:What are spider appendages says:Spiders have spinnerets near the rear end of their bodies. They use these spinnerets to spin out their silk. They have eight legs, and each leg is terminated (depending on the species) by either three claws or two claws. Between the front two legs are two more, shorter, appendages called "pedipalps." These appendages are shorter than legs and are used for manipulating things such as their prey, things they want to eliminate from their webs and living areas, and (in males) they are terminated by a kind of biological syringe that they load up with semen and then inject into the sexual organ of the female during mating. Finally, there are the two chelicerae have a basal part that you can see when you look a resting spider directly in the face, and each of them has a fang that has its point held near the mouth of the spider and that folds into the chelicera like the blade of a jackknife folds into its handle.Unlike insects, spiders do not have antennae. They do not have wings. They do not have three body parts either, just the abdomen and the "cephalothorax" (head plus chest) where the legs, pedipalps, chelicerae, eyes, etc. are located.Read more: What_are_spider_appendages
It's possible that you are describing a jumping spider. Jumping spiders are small and can be black and white in coloration. Some species may have bright green chelicerae (mouthparts), which can appear like "green teeth." These spiders are relatively harmless and are known for their amazing jumping ability.
Chelicerae.
Probably a typo of spider, they are an arachnid, Spidersare air-breathing arthropods that have eight legs, and chelicerae with fangs that inject venom
It would either have to be a hexagon or an octagon. I'm not a hundred percent sure.
Because they come from a different order, Araneae. Like Scorpions and Harvestmen. They are Arthropodsthat have eight legs, and Chelicerae with fangs that inject venom. They are the largest order of the Arachnids.
Arachnids such as spiders and scorpions have chelicerae.
Spiders obtain their food primarily through their mouthparts, specifically a pair of specialized structures called chelicerae. These chelicerae often contain fangs that inject venom into their prey, which is typically insects or other small animals. The venom helps to immobilize the prey and begin the digestion process, allowing the spider to ingest the liquefied tissue. After injecting venom, spiders often use their silk to trap or secure their prey before consuming it.
A garden Spider Has 8 Legs
Trapdoor spiders are heavy-bodied and they also have heavy chelicerae, the parts that the fangs are attached to. They don't have teeth stuck in jaws the way we do, but their chelicerae have tooth-like protrusions that help the spider chew up its food. So the spider will first wrap its prey in silk and then start chewing and at the same time will release some digestive fluid. It will end up with a sort of smoothie. Its stomach can act like a syringe to pull things into it. Spines make a filter that keeps all but the non-solid stuff from getting into the spider's stomach. In the end there will be a little bag of solid body debris, which the spider will dump out its front door.
The prey is captured by the pedipalps and the sting is inserted in it, the paralyzed or killed prey is sucked using the chelicerae.
Chelicerae are the ends of celery that you don't eat. Pedipalps are pedicures that involve a pulp foot massage.
From the phylum of arthropods is where the Spiders belong, it has chelicerae with fangs that inject venom and has eight leg. This air-breathing arthropods has 10 types, and based on science studies, an average spider has 2,230,000 cells.
Spiders with long front legs have a unique characteristic called "elongated chelicerae," which are their mouthparts that help them catch and hold onto prey. This feature sets them apart from other spider species and helps them in hunting and feeding.
