I received the book '1,227 QI FACTS To Blow Your Socks Off' for my birthday. I quote from page 69: At the outbreak of the Second World War, zookeepers killed all the poisonous insects and snakes in London Zoo, in case it was bombed and they escaped. Anyone heard about this before?
Yes, in connection with maximal lengths in king cobras, as the longest yet officially documented specimen was among them.
Yes, destroying the venomous snakes at the outbreak of World War II, has been well documented in books about the history of London Zoo.
I think it's mentioned elsewhere on here that some animals were moved to Whipsnade; no doubt someone can enlighten us further
I don’t think so although, bizarrely, the manatees were destroyed. See the thread below for details of the giant pandas being sent to Whipsnade during the war http://www.zoochat.com/38/what-happened-london-zoos-last-pandas-99519/
Maybe they thought the pool was liable to drain in the event of a bomb strike and this was a humane measure to prevent the possibility of suffocation? Seems a little extreme.
.....venomous snakes killed.... Most of the Aquarium was closed down, and this may have influenced the fate of the Manatees.
What kind of "poisonous insects" would the zoo have had? Are they talking about venomous spiders and scorpions?
yes, spiders and scorpions; specifically black widow spiders are repeatedly mentioned in sources, probably because they are the most notorious. It wasn't only the zoo's animals which were killed - apparently hundreds of thousands of household pets (cats and dogs) were killed by owners distraught at the thought of what might happen to them otherwise: Panic that drove Britain to slaughter 750,000 family pets in one week | Daily Mail Online That article mentions more London Zoo animals: This is an original news report from the Daily Telegraph from September 1939:
I found this also: The first British casualties of war in 1939 The London Zoo site has more as well (of course): https://www.zsl.org/blogs/artefact-of-the-month/zsl-london-zoo-during-world-war-two
It seems strange to have destroyed fruit bats and a muntjac (which I believe was already wild in the uk) and yet keep Komodo dragons and pythons.
It is interesting that you specifically mention king cobra. At Edinburgh Zoo, too, the Council ruled that all the venomous snakes should be destroyed at the start of the war. However, the Director of Edinburgh Zoo, T. H. Gillespie, was particularly fond of a king cobra named “Rebekah” so, ignoring the Council’s instructions to destroy all the poisonous snakes, he refused to have this individual killed.
