In addition to the mouthparts, the capitulum contain chelicera (appendages on each side of the mouth) that pierce, tear, or grasp host tissues and protect the hypostome; pedipalps (a pair of jointed appendages) that aid feeding; a hypostome (ventral fusion of the pedipalps) that helps anchor the tick to the host; and a rostrum that extends dorsally over the mouth.
Once the prey has been captured and subdued, it is transferred to the mouth parts by the pedipalps, large claws that resemble those of a lobster.
Spiders have a pair of jointed appendages (called pedipalps or palps) on either side of the chelicerae that look like short legs.
