Keep your hands to yourself! That's what the bright blue rings on this tiny terror say. These small octopuses prefer to hide in equally small corners or crevices in their ocean home, but if they're caught outside, they'll bite--and that bite is more deadly than that of almost any other creature on Earth. In this volume, full-color photos show these creatures' distinct and bright coloring, and detailed text explains more about how such a small creature can be so dangerous.
