FIGURE 13 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 13. Early development of the Albemarle turtle leech. Shown are unfed, unpigmented embryos of varying ages depicting progressive changes in foregut and crop caeca. A, 4.4 mm (PM-15e), ventral view. B, 4.8 mm (PM-6b), dorsal view. C, 6.0 mm (PM-15h), ventral view. In specimen A the cuticle (cu) separated from the anterior part of the body during preservation. The proboscis (p) is already relatively long and penetrates through the brain (b). The relative length of the proboscis is corroborated by the long cuticle lining the proboscis sheath (cup) emerging from the mouth. Scale bars: 0.5 mm.
