Tortles are humanoid tortoises. They walk upright with a ponderous, rolling gait. The creatures have leathery, reptilian skin and shells that cover their backs and bellies. An adult Tortle stands just under 6 feet tall and weighs more than 750 pounds.
Tortles have no hair; their skin is mostly olive or blue-green. Their back shells are usually shinier and darker than their skin, while their front shells tend to be lighter, with a yellowish cast. A Tortle's mouth is beak-like and toothless and can deliver a vicious bite.
Tortles are stocky, but most of their weight comes from their shells, so they tend to remain at the same weight throughout their adult lives, never growing fat or thin. Their arms and hands are shaped like those of humans, but thicker. Tortles can wield most weapons as easily as humans, though they usually do not wear clothing, only sometimes wearing cloaks, belts, or harnesses for carrying tools and supplies.
