To accommodate this expansion, cell division takes place to facilitate enlargement of the cuticle.
Ticks can transmit an array of infectious diseases that affect humans and other animals.
To keep from dehydrating, ticks hide in humid spots on the forest floor or absorb water from subsaturated air by secreting fluid produced by the onto the external mouthparts and then reingesting the water-enriched fluid.
During feeding, any excess fluid is excreted by the coxal glands, a process that is unique to argasid ticks.
The gnathosoma is a feeding structure with mouthparts adapted for piercing skin and sucking blood; it is the front of the head and contains neither the brain nor the eyes.
