The scientific name for an arachnid's mandibles is 'chelicerae'. Literally, the word means 'claw horns'.
Probably a typo of spider, they are an arachnid, Spidersare air-breathing arthropods that have eight legs, and chelicerae with fangs that inject venom
Arachnids generally share the following traits: eight legs, two body segments, no antenna or wings, have a chelicerae and pedipaips. There are a few species of mites that have all of the above except for eight legs.
Arachnids such as spiders and scorpions have chelicerae.
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.
Spiders share the same characteristics as others in the chelicerae subphylum including using a pointed appendage to grasp food. All chelicerata, including spiders, have six pairs of appendages that are not branched.
