Magnified 98X, this scanning electron microscopic (SEM) image provided a close view of a male Dermacentor sp. tick found on a cat in 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 this tick’s eight legs, placing it into the phylum Arthropoda, and the class Arachnida. From proximal to distal location, each leg is comprised of a coxa, trochanter-1, trochanter-2, a femur, patella, tibia, a two-sectioned tarsus, and a two-part pretarsus, i.e., a pulvillus and claw. Here, we see the trochantofemoral joints of the tick’s left 3rd and 4th legs, and the femoropatellar joints of its left 2nd and 3rd legs.
