The fingers may also have a flexible joint in the middle, permitindo maior destreza e amplitude de movimento. On the tip of each finger there may be a small rounded pad or a retractable claw-shaped structure, that can serve a variety of purposes, como agarrar, manipulate objects or even for defense mechanisms. The alien's hands would likely have a different coloration or texture than human hands, Depending on the species. Eles podem ter uma textura de pele escamosa ou lisa e podem apresentar uma variedade de cores, patterns or even bioluminescence, depending on the alien's environment and evolutionary adaptations. No geral, These three-fingered hands would be specialized for the specific needs of their alien species and could be able to perform complex tasks, Just like the human hand.
