Several years ago I read a magazine article, possibly in National Geographic or Natural History, about exploration in Antarctica. The highlight of the article was the "discovery" of "ice-boring voles". Apparently the researchers had observed penguins and even mammals suddenly disappearing through the ice blocks that they were standing upon. Closer inspection showed that voles had gathered beneath the ice, and using the heat of their noses, had melted the ice so that the hapless creature standing above would fall in the water, and would then be eaten by the voracious voles.
I wish I had saved that article because I was never able later to find anything about the strange Antarctic voles on the internet or in books or magazines.
I wish I had the imaginative power to have fabricated this idea but unfortunately stories of this caliber are beyond my measly capabilities. Can someone help me track this story down, or at least, has someone else out there read that magazine article too?
