Under normal osmolarity conditions, AQP-8::GFP localized within the excretory cell soma and throughout the entire anterior excretory canal. Within the posterior excretory canal, the signal intensity decreased from the soma toward the tail region, although the canal is fully extended throughout the whole body in adults (Khan et al., 2013; Kolotuev et al., 2013). In most animals, the signal was only visible along ~80% of the length of the posterior canal.
