RESUMEN
Tras haberse reportado similitudes estructurales entre las nefronas de dos especies de crocodílidos poco relacionadas taxonómicamente, pero con hábitat similar, Caiman crocodilus crocodilus y Crocodilus acutus, y con el fin de determinar si estas estructuras ofrecen a C. c. crocodilus cierta ventaja en su capacidad de adaptación al hábitat, se llevó a cabo el estudio histológico del riñón de nueve babas macho adultas y de una hembra adulta, usando las coloraciones Hematoxilina-Eosina y tricrómica de Mallory. Entre otros hallazgos, se demostró la existencia de estructuras histológicas que permiten sugerir la presencia del aparato yuxtaglomerular en esta especie.
ABSTRACT
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.
