In the horse breeding industry, the term "half-brother" or "half-sister" only describes horses which have the same dam, but different sires.

[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 ...
The height of horses is measured at the highest point of the withers, where the neck meets the back. [23] This point is used because it is a stable point of the anatomy, unlike the head or neck, which move up and down in relation to the body of the horse.
Pregnant male seahorse. Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes and males producing smaller gametes ().
Icelandic horses weigh between 330 and 380 kilograms (730 and 840 lb) [2] and stand an average of 13 and 14 hands (52 and 56 inches, 132 and 142 cm) high, although the shortest measured Icelandic horse was 113cm (11.1hh), and the tallest measured 157cm (15.3hh).

Some animals, such as the human and northern gannet, do not reach sexual maturity for many years after birth and even then produce few offspring. Others reproduce quickly; but, under normal circumstances, most offspring do not survive to adulthood.
The commission received more than 34,000 public comments opposing the harvest of female horseshoe crabs. Leading scientists also have denounced the commission’s computer model, which recommends ...
The evolution of the horse, a mammal of the family Equidae, occurred over a geologic time scale of 50 million years, transforming the small, dog-sized, [1] forest-dwelling Eohippus into the modern horse. Paleozoologists have been able to piece together a more complete outline of the evolutionary lineage of the
