Tsemu

Tsemus, a.k.a. "Nimbus Horses" or just "Horses", are a species of quadrupedal equinoids which inhabit Nimbus III and can be used for transportation.

Biology
They physically resemble Earth horses, but can be easily identified by their blueish coloration and horns on their heads.

Like several species, Tsemus can be temporarily incapacitated by a Vulcan nerve pinch.
