There are five specific strains of the Arabian horse:
The Kuhaylan (or Keheilan)
This pure-in-strain recognizable features are distinctive deep chest,
macho horsepower and larger size that sets it apart from other
horses. It stands 15 hands and has slightly shorter head and wide
jaws. It is gray or chestnut.
It has a somewhat stylish feminine quality and possesses a fine bone
structure and longer face and neck. It stands 14.2 hands. While galloping
the horse kinks its feet in the air. It has a silky coat which probably
accounts for its name. Dominant colour is Bay.
The Obeyah (or Abyan)
The high tail of this horse daring a sprint almost “carries
the cloak of the rider”, that’s how it got its name Abyan
(meaning a cloak). It is a close cousin of the Seglawi in refinement.
The longer back differentiates it from the typical Arabian horse.
It stands 14.2 hands. The common colour is gray with some white as
if sprayed on.
It has a bigger bone structure, but is somewhat plain with a muscular,
sporty build. The profile is not very “dished” but
somewhat straighter. Stands 15.2 hands. Colour gray and bay.
Gentle strain with close affinity to Hamadani in build and structure
but a smaller version, sharing big bone and muscular build. Stands
14.3 hands. Colour brown or bay with few if any white markings.
