Loggerhead musk turtle only, not on the throat. "Sternotherus minor" lives in clean freshwater habitats such as springs, streams, and rivers. "S. minor" is oviparous. Hatchlings have a straight carapace length of . They have three prominent keels on the carapace, and they have a pinkish unmarked plastron. Two subspecies are recognized, including the nominotypical subspecies. "Nota bene": A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than "Sternotherus". <br>.

History of manifolds and varieties History of manifolds and varieties The study of manifolds combines many important areas of mathematics: it generalizes concepts such as curves and surfaces as well as ideas from linear algebra and topology. Certain special classes of manifolds also have additional algebraic structure; they may behave like groups, for instance. In that case, they are called Lie Groups. Alternatively, they may be described by polynomial equations, in which case they are called algebraic varieties, and if they additionally carry a group structure, they are called algebraic groups. The term "manifold" comes from German "Mannigfaltigkeit," by Riemann. In English, "manifold" refers to
