Umrachs were large reptilian bipeds, introduced to Coruscant when the Yuuzhan Vong Vongformed the planet into Yuuzhan'tar. These creatures inhabited the lower levels, and often fed upon Coruscanti.
The umrach had two muscular hind limbs and two spindly forelimbs which were used to catch prey. The creature hunted by ambushing its victims from above, killing them with its razor-tipped mouth tentacles. These tentacles could reach up to four meters.
Gengi Tung kept two pet Umrachs, Toi and Tixo.
