The aylak (plural aylakim) are small lifeforms, scavenger animals native to planet Vulcan. The aylak are palm-sized, dark brown in color, and have six clawed legs and two whiplike tails. They tend to live in the driest parts of Vulcan, and often perish for lack of water. Dead aylakim serve as a primary part of the diet of the le-matya.
