The Tuskens, also known as Sand People, are a humanoid species native to the planet Tatooine in the Star Wars universe. They are a nomadic and aggressive species, and are often portrayed wearing masks and heavy clothing to protect themselves from the harsh desert environment of their home planet.

Without their masks, Tuskens have distinct physical features that make them easily recognizable. They have a tall and lean build, with an average height of around six feet. Their skin is a dark brown color, rough and textured like sandpaper, and is covered in coarse fur. This fur serves as insulation against the extreme temperatures of the desert and helps them blend into the environment.
The Tuskens have a unique cranial structure, with elongated heads and prominent ridges on their foreheads. These ridges are believed to be a form of protection, both from the harsh environment and from potential predators. Their eyes are small and slanted, and their ears are large and pointed, giving them excellent hearing in the vast expanses of the desert.
Their faces are adorned with various tribal tattoos and markings, which are unique to each individual and are a sign of status and identity within their culture. They also have sharp teeth and claws, which are used for hunting and defense.
In addition to their physical features, the Tuskens also have a distinct cultural identity. They are a nomadic people who live in small family groups and travel across the desert in search of food and water. They are skilled hunters and gatherers, and their diet consists mainly of desert creatures and plants.
Their society is organized around a strict hierarchy, with the strongest and most skilled members holding positions of power and authority. They have a deep reverence for their ancestors and the natural world, and their culture is steeped in tradition and ritual.
Overall, the Tuskens are a unique and fascinating species in the Star Wars universe. While their aggressive nature and nomadic lifestyle may make them appear primitive to outsiders, they have a rich cultural history and a deep connection to the harsh desert environment that has shaped their physical appearance and way of life.
