I've just found out about the existence of Tardigrades, also known by the rather cuter names of water bears and moss piglets. I was surprised that they live all over the planet because I've never seen one. Then I found out that the biggest is less than a couple of millimetres long. Ah that explains it! My eyesight is so poor these days that I could have difficulty spotting a new born kitty let alone something that could sit on top of a pin. But if you want to go and spot them here's useful advice from a wonderful newly discovered website 'The Kid Should See This'.
These critters are tough. They can survive extremes of temperature and pressure, radiation and dehydration. I don't really want to think about the experiments that they might have been subjected to so that these facts could be discovered. I was going to elaborate much more on their super survival strengths but in the process of researching this post I came across this.
Someone has knitted a woolly tardigrade complete with eight legs and a weird nose. Now isn't this one of the most wacky knitting projects ever?
