DescriptionPhilobdella floridana (10.11646-zootaxa.4544.2.3) Figure 6.png |
English: FIGURE 6. Comparison of digestive tracts of Philobdella floridana from North Carolina (Lake Phelps) (A) and South Carolina (Santee Swamp) (B), and their respective relationships to their urinary bladders. A, Dissected specimen Phg-2 showing prominent urinary bladders adhering to the anterior crop caeca of segments XV–XIX, respectively, and to the elongated posterior caeca of segment XIX (enteronephric). B, Dissected specimen Psa-1 showing that the 17 pairs of urinary bladders are physically independent of all crop caeca (i.e. not enteronephric). Note in both specimens the crops are dichotomous, i.e. an anterior and a posterior pair of caeca per segment. In specimen B the anterior caeca of segments XII and XIII are depicted descending to the ventral body floor; similar descension of these respective caeca also occurred in specimen A but is not depicted. Solid circles, segmental ganglia of ventral nerve cord, depicting ‘brain’ I–VI: ventral chain, VII–XXVII; tail mass, XXVIII–XXXIV. |
