摘要: Abstract We examined comparative skin permeability by measuring cutaneous water loss and epidermal lipid content of two sympatric snake congeners, the Southern Copperhead (Agkistrodon contortrix) Western Cottonmouth (A. piscivorus). Samples shed epidermis from each species were taken to first investigate species-specific differences. Shed samples multiple regions along dorsal ventral integument then used examine potential variation in among different body for species. Rates significantly higher A. piscivorus. In addition, rates piscivorus differed region (i.e., anterior, mid, posterior) surface ventral) with highest mid-dorsum. Lipid did not differ between However, varied surfaces both species, greater ...
