Description:Caption:
Magnified 3862X, this scanning electron microscopic (SEM) image depicted the recessed base of a single seta, or sensory hair, emanating from the dorsum of an unidentified male Dermacentor sp. tick found upon a cat in the suburbs of Decatur, Georgia, which measured approximately 3.5mm from its gnathosoma, which is where its mouthparts were located, to the distal abdominal margin (PHIL 9961). PHIL 9959 revealed all eight legs, placing it into the phylum Arthropoda, and the class Arachnida. Setae are chitinous exoskeletal adnexae, which being sensorial in nature, sense environmental changes in temperature, movement, i.e., wind, and chemistry, i.e., pheromones.
