→Second take on the Kroot
The limited specimens that have been made available for study are found to have brains composed of a front and rear hemisphere. It appears that the larger, frontal hemisphere controls the functions of logic, reasoning and memory while the rear, less developed hemisphere is more attuned to imagination and creativity. If this is indeed the case, it would go some way to explaining the pragmatic approach to life of the Kroot and their current technological stagnation. The Kroot head is crowned with a great mass of tough, flexible quills that appear to be a part of the Kroot's sensory apparatus. These quills contain what seem to be ganglia running from the frontal lobes of the alien's brain and, in this position, would be extremely efficient at receiving and interpreting information on the surrounding environment. The olfactory cavity within the Kroot skull is also enlarged, with multiple sense organs within both it and the mouth. Their eyes are without pupils and generally a milky white. It is likely that they are able to see further into the infrared end of the spectrum and can sense the body heat generated by their prey. Therefore, the Kroot make excellent trackers and would be extremely difficult to sneak up on.
The Kroot generate little in the way of waste, excreting in the form of a pungent, oily sweat that has a variety of properties, depending on what the Kroot has consumed. The most apparent benefits are that this sweat appears to be heat retardant to a degree, has antibiotic properties and can cause a poorly aimed blow to slide clear. It is suspected that the Kroot can alter the properties of this secretion in order to leave pheromone trails, mark territories, leave warnings and even communicate with one another. This may also be some form of control that extends to lower life forms such as birds and animals, as there is evidence to suggest that the Kroot employ empathic pheromones to prevent such creatures from being startled by them and giving away their position in battle. Combined with this method of communication, the Kroot can learn new languages at an astounding rate, matching posture and tone to the sound of foreign words in order to discern their meaning. Their own verbal communication is a mixture of clicks and whistles, possibly reinforced by these phenomena pheromone exudations.
By far the most odious habit of the Kroot is their practice of eating the flesh of the dead. In battle, this leads them to ritually devour the corpses of those they have killed, and almost nothing is beyond their tastes. The Kroot digestive system is extremely efficient, capable of breaking down almost any organic material into an energy form that can be stored in specialized organs scattered throughout their bodies called nymnes. Should anything inorganic and indigestible be consumed, the Kroot must regurgitate it, with considerable discomfort. However the strangest quirk of Kroot digestion is their ability to extract potentially useful strands of their food's DNA. Adeptus Mechanicus Genetors have long been aware that much of the double helix structure of DNA is in fact blank and used to separate those areas that do contain genetic information. The Kroot have somehow inherited the ability to incorporate useful DNA codes into their own genetic make up. Larger Kroot, called Shapers, who have an instinctive understanding of this process, can direct their kindred to consume certain prey in order that in successive generations, they may take on elements of those genes.
