The expert veterinary team at London Zoo have x-rayed 18,000 animals and made some of the images available to the public.
What they inadvertently discovered, however, was that there is a staggering amount of inter-species drug dealing occurring within zoo walls.
The images show the inner workings of a variety of different species, including frogs, snakes, geckos and turtles.
But experts were left stunned when closer examination of the images revealed some of the animals to be carrying various drugs and stashing their gear inside their bodies, well out of the view of the zookeepers.
“We can tell so much about an animal’s health from looking at an x-ray; from the strength of their bones to how healthy their heart is,” said zoo spokeswoman Anita Tokeweed.
“And we can also see where some of them are hiding their drugs. Just look at this x-ray of one of the kangaroos – in his pouch he’s got a pound of ganja, two wraps of heroin and a Tupperware pot of amphetamines.”
Interestingly, the zoo mules were found to be carrying no drugs at all, whereas the polar bears were each found to be concealing cocaine in their fur with a street value of over quarter of a million pounds.
”No wonder the pandas aren’t mating, they’re off their heads half the time” said Ms Tokeweed.
“And we think the pelicans are distributing the drugs around the zoo, after we discovered that one was carrying nearly three kilograms of heroin in it’s beak, the crafty bastard.
“So from now on, all animals will be strictly vetted, and we’ll be closely vetting the vets, too.”
