In the wild, these beasts also obtain calcium from the consumption of dried snail shells, bleached bones, and limestone particulate. Sunlight is also a crucial source of D3, which is converted to useable calcium through a process initiated by thermal radiation, another energy source from the sun. The sun is, therefore, the most immediately important source of calcium. Without sunlight or an adequate substitute light source, sulcatas simply do not thrive.
