FIGURE 9 in Description and taxonomic analysis of a tuberculated turtle leech from the Outer Banks, North Carolina, USA, provisionally identified as Placobdella multilineata Moore, 1953 (Hirudinea: Glossiphoniidae)

FIGURE 9. The eyes of the Albemarle turtle leech develop remarkably early in the embryo, long before any other pigment is discernible. Shown are the eyes of an early embryo (4.5 mm, PM-9) at different magnifications. A, head region showing one apparent pair of contiguous eyes. B, C, higher magnifications reveal the eyes are actually compound, each comprised of a smaller anterior and larger posterior eye. Scale bars: A, B, 0.1 mm; C, 20 μm.
