Nanomorphology of horny scale of Dipsadinae snakes (Squamata: Colubridae)

This study focuses on the analysis of the nanostructure of the horny scales in four species of snakes of the subfamily Dipsadinae from Argentina, examining the microscopic characteristics of the surface of the cephalic and body scales by scanning electron microscopy (SEM). The results reveal a confi...

The results reveal a configuration of cellular morphotypes in the scale hinge and basal areas common to all scales and species analysed; cellular variability was observed in the apical region of the scales, where different cellular morphotypes were identified in the various taxa. This structural variability, as well as the presence of microornamentations (microtufts, ridges, or raised structures), point to intergeneric microstructural differences that could be related to both phylogenetic and functional factors, specific to each type of scale in response to the environment where the species inhabit.  Este estudio se enfoca en el análisis de la nanoestructura de las escamas córneas en cuatro especies de serpientes de la subfamilia Dipsadinae de Argentina, examinando las características microscópicas de la superficie de las escamas cefálicas y del cuerpo, mediante microscopía electrónica de barrido (MEB). Los resultados revelan una configuración de morfotipos celulares en la bisagra de la escama y en sus zonas basales común a todas las escamas y especies analizadas; la variabilidad celular se observó en la región apical de las escamas, donde se identificaron distintos morfotipos celulares en los diversos taxones. Esta variabilidad estructural, como así también la presencia de microornamentaciones (microquillas, crestas, o estructuras elevadas), señalan diferencias microestructurales intergenéricas que podrían estar relacionadas tanto con factores filogenéticos como funcionales, específicos de cada tipo de escama en respuesta al ambiente donde habitan las especies.
