Scorpions have similar tastes in burrow architecture

New research on the burrows of scorpions in diverse environments finds that these predatory arachnids build strikingly similar architectural features in their homes. The study was conducted using molten aluminum casts and 3-D scanning, and suggests that common features of scorpion burrows are part of their 'extended physiology' and are vital to the arachnids' survival in some of the world's most inhospitable places.
