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 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 do chelicerae and pedipalps do?
The prey is captured by the pedipalps and the sting is inserted in it, the paralyzed or killed prey is sucked using the chelicerae.
Where would you find the mandibles of an insect?
Mandibles are jaws. Find the mouth and you will find the mandibles.
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.
How many mandibles do grasshoppers have?
Grasshoppers have two mandibles. These are the insect's mouthparts that are used for biting and chewing food.
What do arachnids have instead of mandibles?
The scientific name for an arachnid's mandibles is 'chelicerae'. Literally, the word means 'claw horns'.
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.
What is the difference between chelicetara and other arthropods?
Chelicerae are specialized feeding appendages found in chelicerates, a subphylum of arthropods that includes spiders, scorpions, and horseshoe crabs. They are used for grasping and tearing food. Other arthropods, such as insects and crustaceans, have different types of mouthparts for feeding, like mandibles or maxillae.
Which arthopods have chelicerae?
Arachnids such as spiders and scorpions have chelicerae.
What is the difference between mandibulates and chelicerates?
They have different mouth parts used for feeding. Mandibulates have mandibles, or opposing mouthparts which are like jaws. Cherlicerates have pincer-like mouthparts (cherlicera).
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.

What is the mandibles function?
Mandibles are used to crush food.
What do chelicerae and pedipalps do?
The prey is captured by the pedipalps and the sting is inserted in it, the paralyzed or killed prey is sucked using the chelicerae.
Do whales have mandibles?
Yes. The lower jawbones are the whales mandibles
What is the function of mandibles in arthropods?
Mandibles are jaws and are used for eating.
Do fly's have mandibles?
yes they have mandibles that can be seen if you look closely.
