CABRERA A, Francisco J  e  GARCIA C, Gisela C. Histology of the Spectacled Caiman Kidney (Caiman crocodilus crocodilus). Rev. Fac. Cienc. Vet. [online]. 2009, vol.50, n.2, pp.207-212. ISSN 0258-6576.

Structural similarities have been reported between the nephrons of two crocodrilian species (Caiman crocrodilus crocrodilus and Crocodilus acutus) not taxonomically related, but with a similar habitat. A histological study of the kidney was conducted to determine if these structures give the C. c crocodiles certain advantages in its capacity for adaptation to the habitat. Nine adult male and one adult female caimans were used in the study. Samples were stained with hematoxilin-eosin and Mallory’s tricromic stains. The results of the present study reveal the presence of microscopic structures that suggest the existence of a juxtaglomerular apparatus in this species.
