What does chelicerata mean?
Chelicerata is a subphylum of the phylum Arthropoda. It contains organisms like spiders, ticks, and scorpions. Organisms in Subphylum Chelicerata have a cephalothorax and a posterior abdomen. They have six pairs of appendages on their cephalothorax: Chelicerae, pedipalps, and four walking legs. Chelicerae are pinchers that crush food, and pedipalps are appendages that control food. They do not have mandibles, which are jaws, and they don't have antennae, so organisms in Subphylum Chelicerata technically aren't insects.
What does a spider use its chelicerae for?
A spider uses its chelicerae to catch its prey by stabbing it and injecting venom into it.
What kind of appendages do spiders have?
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

What is the difference between chelicerae and mandibles?
Chelicerae and mandibles are both types of mouthparts found in different groups of arthropods. Chelicerae are characteristic of arachnids (like spiders and scorpions) and typically consist of two segments, often functioning as pincers or fangs. In contrast, mandibles are found in crustaceans and insects, featuring a pair of jaw-like structures used for biting, chewing, or gripping food. The key difference lies in their structure, function, and the groups of animals that possess them.
What is the difference between chelicerae and pedipalps?
Chelicerae are the ends of celery that you don't eat. Pedipalps are pedicures that involve a pulp foot massage.
Directly behind the chelicerae spiders have a pair of appendages called?
pedipalps
Why are horseshoe crabs in the subphylum chelicerata and why are they unique?
Horseshoe crabs are in subphylum Chelicerata because they have four pairs of walking legs, a pair of pedipalps, and a pair of chelicerae. Pedipalps control food, and chelicerae are pinchers that crush food. Horseshoe crabs also don't have mandibles, which are jaws, and they don't have antennae. They have two tagmata: cephalothorax and abdomen. All of these characteristics apply to organisms in subphylum Chelicerata, and so horseshoe crabs are in subphylum Chelicerata.

How many body segments do garden spiders have?
A garden Spider Has 8 Legs
Which arthopods have chelicerae?
Arachnids such as spiders and scorpions have chelicerae.
Do spiders or scorpions have larger pedipalps?
Scorpions have larger pedipalps becasue they do!
What is the name of the head structure that a spider does not have common with other arthropods?
The head of a spider is called the cephalothorax ('head-chest'), as it also contains the chest structures such as the legs. Though, spider fangs are also unique among arthropods, these are also called chelicerae; and the pedipalps next to them don't have a counterpart in other groups either. In scorpions, the pedipalps are modified into pincers, but in spiders they look like little legs and are used to manipulate food etc.
What are the functions of the spider's pedipalps?
Pedipalps have been adapted for feeding, locomotion, and/or reproductive functions.
Are the tube thats carry oxygen in arthropods are called pedipalps?
NO. Pedipalps are adapted for handling food and for sensing.In male spiders, pedipalps are further modified to carry sperm during reproduction.
How many legs do arachnids have?

When a spider bites it uses its?
Chelicerae.
