What unique parasitic role defines ticks within the Acari group?
Answer
Being the only known blood-feeding ectoparasites
Ticks occupy a unique and highly adapted position within the broader class of arachnids because they are the sole known lineage within the Acari group whose existence is defined by obligate blood-feeding ectoparasitism. This commitment required significant genomic and physiological restructuring dedicated almost entirely to acquiring, processing, and managing the influx of nutrients and fluids from blood meals. This fundamental specialization is what separates them evolutionarily from their mite relatives, demonstrating a definitive blueprint for survival based entirely on hematophagy that has persisted over hundreds of millions of years.
