Arachnids such as spiders and scorpions have chelicerae.
Animals with outer shells and segmented bodies are members of the phylum arthrapoda. This phylum includes insects and chelicerae's (spiders, millipedes, etc.).
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.
Chelicerae are the ends of celery that you don't eat. Pedipalps are pedicures that involve a pulp foot massage.
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.
A spider uses its chelicerae to catch its prey by stabbing it and injecting venom into it.
Scorpions have a unique mouth structure that consists of a pair of pincers called pedipalps and a set of chelicerae, which are small, claw-like appendages. Their mouthparts are adapted for grasping and tearing prey, allowing them to consume insects and other small animals. Scorpions do not have jaws like mammals; instead, they use their chelicerae to manipulate food before ingesting it.
