Photos demonstrating our dissection technique:

Download Stage one of dissection: tiny incisions are made around the edge of the scutum (i.e. back-plate or shield), which is then peeled back to reveal the inside of the tick. Salivary glands near the mouth (white) and the gut (dark red/brown network) are visible.
