LONGEVITY SURVEY LENGTH OF LIFE OF MAMMALS IN CAPTIVITY AT THE LONDON ZOO AND WHIPSNADE PARK The figures given in the following tables are based on the records of the Zoological Society of London for the years 1930 to 1960. The number of specimens in each sample is given in the first column. The percentage of the sample that died in less than a year at the zoo is iven in second column. In this way ‘delicate’ zoo species can be noted at a glance. An average fife span of all those individuals living for more than a year at the zoo is given (in months) in the third column. In the fourth column the maximum individual life-span is noted for each species. It must be emphasized that the age of specimens arriving at the zoo is seldom known accur- ately and no allowance has been made for this. All figures refer to the period of time between arrival at the zoo and death at the zoo. Actual life-spans will, therefore, usually be longer than those given.
