A horse can have between zero and four canine teeth, also known as tusks (tushes), with a clear prevalence towards male horses (stallions and geldings) who normally have a full set of four. Fewer than 28% of female horses have any canine teeth. Those that do normally only have one or two, and these may be only partially erupted. [3]
Bilaterians likely evolved from an ancestor that was radially symmetrical. There have been suggestions that the blastopore started out as the digestive surface on a radial organism that became elongated (and thus bilaterally symmetrical) before its sides closed over to leave a mouth at the front and an anus at the rear.

1860 engraving depicting the performing horse Marocco. A significant portion of medieval technical literature consists of treatises on veterinary care. [S 11] Arab and Muslim scholars made notable contributions to the knowledge of equine medicine, education, [5] and training, in part due to the contributions of the translator Ibn Akhî Hizâm, who wrote around 895, [6] and Ibn al-Awam, who ...
There is an empty interdental space between the incisors and the molars where the bit rests directly on the gums, or "bars" of the horse's mouth when the horse is bridled. [67] An estimate of a horse's age can be made from looking at its teeth. The teeth continue to erupt throughout life and are worn down by grazing.
In the horse breeding industry, the term "half-brother" or "half-sister" only describes horses which have the same dam, but different sires. [6] Horses with the same sire but different dams are simply said to be "by the same sire", and no sibling relationship is implied. [7] "Full" (or "own") siblings have both the same dam and the same sire.
Grass is a natural source of nutrition for a horse. Equine nutrition is the feeding of horses, ponies, mules, donkeys, and other equines. Correct and balanced nutrition is a critical component of proper horse care. Horses are non-ruminant herbivores of a type known as a "hindgut fermenter." Horses have only one stomach, as do humans.
Free-roaming mustangs (Utah, 2005). Horse behavior is best understood from the view that horses are prey animals with a well-developed fight-or-flight response.Their first reaction to a threat is often to flee, although sometimes they stand their ground and defend themselves or their offspring in cases where flight is untenable, such as when a foal would be threatened.
Considered a crop for cool-temperate climates, the mangelwurzel sown in autumn can be grown as a winter crop in warm-temperate to subtropical climates. Both leaves and roots may be eaten. Leaves can be lightly steamed for salads or lightly boiled as a vegetable if treated like spinach or chard, which is a member of the same subspecies. Grown in ...
