An odd report that the Venus flytrap (Dionaea muscipula) can apparently 'count' in order avoid wasting 'energy' whilst attempting to catch flies, in order to provide scarce nitrogen (http://www.theguardian.com/environment/2016/jan/21/venus-flytraps-able-to-count-in-order-to-avoid-false-alarms-study-finds). I think that this is an odd use of the word count. This vegetable predator doesn't have anything like a nervous system to calculate with but it employs systems with its thigomosensitive (touch-sensitive) hairs and its closure mechanisms (which largely involve rapid movements of water) where priming occurs. One touch to get ready, Two touches to close and More to produce digestive systems.
