Summary: | Skin is the first protection barrier for the frog species that protect them from high temperature, chemical toxics, and over
exposure to sunlight. Thus variation in skin characteristics might reflect their adaptation to environment. Since leaf litter
frogs are facing threats of habitat fragmentation, we investigate the skin structure of the Bornean leaf litter horned frog
Megophrys nasuta, from different body regions. Histological analysis of the frog skins and slide preparations using
Haematoxylin and Eosin staining protocol were employed. Findings indicated that all body regions of M. nasuta skins have
similar characteristics of the strata, epidermis and dermis layers. However, thickness of the epidermis layer and glands
distribution varies between dorsal and ventral (areas that were first in contact with the environment) thus suggesting their
adaptation strategy. The observed distributions of serous and mucous glands on different skin regions might also reflect the
habit of this species in their natural habitat. These results may help in understanding the function of the skin structure to meet
their ecological needs especially in the changing environment at fragmented area. The data should be extended and explored
to study the effects of habitat fragmentation on the amphibians. |
