| Abstract: | - 1.1. The weight and energy content of sloughed skins of 92 individual snakes of 22 different species in three families were measured.
- 2.2. Weight and total energy content of shed skins were highly correlated with body weight.
- 3.3. The heat of combustion (kJ/g) of sloughed skins varied significantly among families and was higher in species having unkeeled scales than in those with keeled scales.
- 4.4. The presence of keels significantly affected weight of skins, even when skin weight is adjusted for covariance with body weight.
- 5.5. Neither body weight nor ambient temperature significantly affected the heat of combustion of sloughed skins.
- 6.6. The energy content of shed skin, expressed as a proportion of daily metabolism, decreased with ambient temperature, but the effect is minimized in large snakes.
- 7.7. Small snakes expended relatively less energy in sloughed skins than large snakes when the expenditure is expressed in terms of total daily metabolized energy.
