The Pelengs are one of the five Coalition races in the Space Rangers series. They're fairly odd-looking by human standards, having yellow/green skin colours, an elongated face somewhat resembling a trunk, with two horizontal slit-like nostrils and a horn on the top/back of the head (similar to the crest seen on a Parasaurolophus). Pelengs are humanoid in stature, however they have four arms and a skinny neck.
Known, perhaps unfairly, as an entirely criminal race, most Peleng planets and governments are said to be lawless and corrupt. Pirates are revered as heroes in Peleng society and children are taught the ways of being a Lyakusha at a young age.
