A question just came in about what ant mandibles look like. Now this might not be something you think about every day, but it really is an interesting topic. I remembered a wonderful website that discusses all the things that ants do with their mandibles and shows some fantastic close up photographs of different species. I do have to warn you, however, it is written for adult scientists. The site is called Diversity of Ant Mandibles.
