Hengists much resemble large horses, except that the backs of their heads have tall ridges, as do their ears. Their fur is also much more scale-like than Terran horses.
These animals can come in many colors, including brown, black, white, red, green, blue, indigo, etc.
Hengists are social creatures that form strong bonds with others of their species.
Hengists have been domesticated by the Wazelians, who use them as mounts and beasts of burden. The inherent sociality of the Hengists made this domestication much easier.
