Table 1 provides a rough estimate of the total weight of 5,157 species of adult male and female mammals alive today and a calculated overall average weight for these adult mammals based on this total. One hundred and thirty (130) marine mammals are not included in the number of species above and calculations as the survival of these marine species in a flood probably would not require an ark.
Estimates are based on as large of sampling as practical using primarily online resources. As adult mammal weights for a particular species can vary considerably depending on age, sex, and other factors, averaging became the preferred method. Rough average adult weights were calculated for each sample species in a group (i.e order, suborder, family, or genus). Then these rough average adult weights were averaged for the group. This group average then was multiplied with few exceptions times the number of species in the group times two to give a total weight for male and female couples in the group. All total weights for the groups were then added together to give the total weight of the female and male adult mammals. The rough overall average weight per mammal was then determined by dividing the latter total weight first by two and then by total number of mammal species, excluding 130 marine mammals.
