Hundreds of people showed up at the extInked event in the UK for a chance to get a tattoo of an endangered species, New Scientist reports. Volunteers had to fill out a form explaining why they should be the one to have a particular endangered species inked on their body. There were 100 species on the list, and only 100 volunteers were chosen. Each tattoo was specially designed and drawn on each participant by an artist from Ink vs. Steel studio.
