 The consumption of mammalian milk, in contrast, is regarded with disgust. Since mammary glands are unconnected to the digestive trait, mammal milk is analogized to mucus or pus. The consumption of eggs, even unfertilized, is also taboo in almost all //'ikra// cultures, with one exception: growing nestlings consume chips of their own eggshell as a crucial source of calcium. Calcium supplements, in form of bonemeal and cuttlebones, are important not only for nestlings but also adults: a chronically calcium-deficient diet will make a female sterile, as her eggs fail to develop a shell and are reabsorbed before being laid.
-Since //'ikra// teeth are scarcely suited to chew starchy or fibrous plant matter, such foods are usually ground, minced, or boiled into gruel. Cellulose-based food, if not used to feed animals or grow mushrooms, may be treated with yeast-like fungi to release simple sugars.

While any small, hard stone will do, polished gastroliths in bone or porcelain are part of any elegant tableware set.

   * The planet is, at least, several hundred thousand or million years old, enough time for sand, mud, and other sediments to consolidate into rock.
   * All living organisms, including the 'ikra, developed gradually over the history of the planet by gradual modifications that result in adaptation to one's environment.
+  * Tagra used to be warmer in the past, when the 'ikra developed from their ancestors (hence the extent of fossil coal deposits, and the inability of 'ikra to survive winter without technology).
 The commonly used units of measurement are based on the traditional Grikaa units, with factors of conversion modified for easier computation (e.g., to be based on the octal numbering system, and often to include 3 or 5 as factors):
