Histología del Ri？ón de la Baba (Caiman crocodilus crocodilus)

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.
