Ticks are obligate hematophagous ectoparasites belonging to the phylum Arthropoda and the class Arachnida. Their feeding on the blood of animals and humans, as well as their capacity to transmit various pathogens, makes them organisms of considerable medical and veterinary importance. Due to their role in disease transmission and unique biological features, ticks are studied in detail in the fields of epidemiology, zoology, and public health.Systematics and TaxonomyKingdom: AnimaliaPhylum: Arthr
