The renal vascular system of the Ball python (Python regius) and the anaconda (Eunectes noteus; Serpentes - Squamata) has been investigated using light microscopy, transmission electron microscopy (TEM), and scanning electron microscopy (SEM) of vascular corrosion casts and critical-point dried non-corroded specimens. The average glomerular diameters of these two species differ significantly (anaconda: 59.1 μm, python: 124.3 μm). Also, the relative proportions of the renal tubules are different. These findings can be related to the different habitats of the two species (aquatic versus terrestrial environment).
