FIGURES 3–9 in Occurrence of Epistylis anastatica (Linnaeus, 1767) (Ciliophora: Peritrichia) on Mesocyclops isabellae Dussart & Fernando (Crustacea: Copepoda: Cyclopoida) in India, with an annotated checklist of species of Epistylis reported as Epibionts of Cyclopoid Copepods and resources for their identification

FIGURES 3–9. Epistylis anastatica attached to the exoskeleton of Mesocyclops isabellae. 3–5: views of the stalk, showing the dichotomous branching pattern and long primary stalk; arrowheads in fig. 3 indicate the branching points in an asymmetrically dichotomous colony and to its right are the abandoned stalks of a symmetrically dichotomous colony (region encircled); 4, immature colony; note the elongate primary stalk; 5, stalks of two symmetrically dichotomous colonies (one is lying over the other, which is slightly out of focus). 6–9: characteristics of zooids; 6, the upper arrowhead indicates the edge of the peristomial lip, and the lower arrowhead indicates the scopula (circular, aboral region that secretes the stalk and attaches the zooid to it); 7, arrow indicates the projecting tube formed by constriction of the peristomial lip when cell contracts ("schnauzenformigen"); MaN, longitudinally oriented macronucleus; 8–9, zooids that remained expanded when fixed; arrow indicates the peristomial lip in both figures. Scale bar = 100 µm in 3–4 and 25 µm in 5–9.
