When talking about unappetizing foods witchetty grub comes to mind. Part of the Australian "bushmeat" type of food, this was a staple of the indigenous Australians in the desert. This can either be eaten raw when it tastes like almonds or lightly cooked, where its skin crisps like roasted chicken and its insides take on the look and consistency of a scrambled egg. Apparently, it tastes much better than it looks. The witchetty grub is valued for its protein content and nutrition.
When held, as a defense mechanism, the grubs will secrete a brown liquid. These grubs live about 60 centimeters (24 in) below ground and feed upon the roots of river red gum. They can also be found under black wattle trees, and are attributed as the reason why the wattles die within 10 to 15 years which is a damn long time for a grub to live. It's almost as long as a dog or cat for that matter.
