| description | This study verified the comparative histomorphometric adaptations in the stomach of rat, bat and pangolin in relation to diet. Ten rats, ten bats and ten pangolins of both sexes were used for this investigation. The animals were sacrificed after slight anesthesia under chloroform inhalation. The stomach were excised, fixed in 10% formol saline and processed for light microscopic study. Stained slides were also subjected to morphometric analysis at a magnification of 400x. The results revealed that the cellular diameter/ density of parietal and zymogenic cells are significantly different in the three mammals (p0.05) when compared with that of rat. Also, histological analysis revealed slight differences in the pattern of organization and distribution of connective tissue fibers. All these observations were reflections of the different pattern the stomachs of the three mammals have adopted to cope with their respective diets. KEY WORDS: Pangolin; Bat; Rat; Stomach; Histomorphometry; Connective tissue fibers. En este estudio se verificaron las adaptaciones histomorfometricas comparativas en el estomago de ratas, murcielagos y pangolines en relacion a la dieta. Se utilizaron para esta investigacion 10 ejemplares de cada especie, de ambos sexos. Los animales fueron sacrificados despues de anestesia bajo inhalacion de cloroformo. Los estomago fueron extirpados, fijados en formol al 10% de solucion salina y procesados para su estudio microscopico de luz. Los cortes tenidos fueron tambien objeto de analisis morfometrico con un aumento de x 400. Los resultados revelaron que el diametro/densidad celular de parietal y las celulas cimogenas son significativamente diferentes en los tres mamiferos (p 0,05) en comparacion con la de rata. Por otra parte, el analisis histologico revelo ligeras diferencias en las caracteristicas de organizacion y distribucion de las fibras del tejido conjuntivo. Todas estas observaciones son un reflejo del patron de los diferentes estomagos de los tres mamiferos, que han adoptado para hacer frente a sus respectivas dietas.
