1. How many animal species have the London Zoo ever kept ? (a number, or a rough estimate).
I wouldn’t like to estimate how many different animal species have been kept at London Zoo although the following may be of interest:-
Between 1862 and 1896 the Zoological Society of London produced nine editions of the book “
List of the Vertebrated Animals now or lately Living in the Gardens of the Zoological Society of London”. Then in 1929, a centenary three volume edition was published that listed every species of vertebrate kept in the zoo between 1828 and 1927.
According to this centenary edition the following number of species had been kept at London Zoo during its first one hundred years:-
- mammals 949
- birds 2330
- reptiles 736
- amphibians 158
- fish 280
With all the taxonomic changes over the last eighty odd years, if a similar list of species covering the years 1828 – 1927 were produced according to today’s taxonomy, the exact number of species would surely be different. Nevertheless, these figures are indicative of the approximate number of vertebrate species kept at London Zoo during its first one hundred years.
Obviously many new species, not featured in this list, have been kept subsequently; a few species of mammals first kept after 1927 immediately spring to mind including:-
okapi; gerenuk; white rhinoceros; mountain gorilla; Philippine tarsier; golden snub-nosed monkey; giant panda; Baikal seal; giant armadillo; Hispaniolan solenodon........
Of course there are a great many other new mammal species and many other new vertebrate species that have been kept since 1927 too.
And, of course, lots of invertebrates........
