Amblyomma is a genus of ticks known for their role as ectoparasites, feeding on the blood of various hosts, including mammals, birds, and reptiles. They are commonly found in tropical and subtropical regions and can transmit diseases to both animals and humans. These ticks are characterized by their distinctive shapes and patterns, with some species having a prominent scutum, or shield-like structure, on their backs. Amblyomma ticks are known to carry pathogens such as Rickettsia and Ehrlichia, which can lead to serious health issues if transmitted through bites.
