A live snail was kept in a museum for years before anyone knew it was alive. In the mid-1800s, scientists found a desert snail and sent it to the British Museum as a specimen. Museum workers thought it was dead, so glued it to a display. The snail was used to starvation and curled up in its shell for hibernation. Four years later, someone noticed the discolored paper, though it shouldn’t have been, if the shell was properly prepared. So, the sleeping snail was discovered. After a warm bath, the snail woke up and lived for another two years, before dying of natural causes.
