ID#: 9976
Magnified 207X, this scanning electron micrographic (SEM) image depicted a dorsal view of an engorged female tick, which had been extracted from a pet cat, while in the process of obtaining its blood meal. This was an enlarged view of the tick's engorged abdomen, revealing the wrinkled, expandable tissue that enables the tick to ingest huge quantities of blood. Note in PHIL 9959 and 9960, that in the case of another tick specimen, its entire dorsal abdomen was covered by its chitinous scutum, or shield, categorizing it as a male. In this specimen, the scutum only partially covered the dorsal abdomen (see PHIL 9972), which identified this tick as a female. Ticks belong to the phylum Arthropoda, and the class Arachnida.
