The zoo also revealed that four meerkats, whose enclosure was nearest to the fire, were unaccounted for, but they are now presumed dead, as well.
Misha the aardvark in London, Britain on December 23, 2017. "We are all naturally devastated by this, but are immensely grateful to the fire brigade, who reacted quickly to the situation to bring the fire under control".
The zoo will remain closed on Saturday until further notice. London Fire Brigade have stated that no animals or people have been injured in the blaze, which began at around 06:00 near the Adventure cafe.
"All other animals in the vicinity are being monitored closely by our vets, but early signs suggest they have not been affected".
London Zoo is on lockdown after a huge blaze ripped through the cafe - next to the beloved meerkats. Aardvarks originate in sub-Saharan Africa and are nocturnal. According to a map of the zoo, the café is adjacent to the meerkat enclosure.
Unfortunately, the zoo confirmed in a statement that a 9-year-old aardvark named Misha perished in the fire.
The New York Times reported that about 70 firefighters were brought in to battle the blaze and contain the damage.
It took 72 firefighters just over three hours to put the fire out.
The fire started shortly after 6 a.m. Saturday, and staff who live on the site immediately started moving animals to safety, officials said.
