Pit latrine - Wikipedia

A pit latrine, also known as pit toilet, is a type of toilet that collects human feces in a hole in the ground. Urine and feces enter the pit through a drop hole in the floor, which might be connected to a toilet seat or squatting pan for user comfort. Pit latrines can be built to function without water or they can have a water seal (pour-flush pit latrine).

Snake - Snake - Form and function: The most characteristic aspect of the snake form is the elongate body and tail and the absence of limbs. There is no snake in which the limb remnants still retain a function in locomotion, but complete or reduced elements of the pelvis and femur remain in many snake families, including the boa and python families.

Limestone: Rock Uses, Formation, Composition, Pictures

What is Limestone? Limestone is a sedimentary rock composed primarily of calcite, a calcium carbonate mineral with a chemical composition of CaCO 3.It usually forms in clear, calm, warm, shallow marine waters. Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris.
