This paper establishes existence theorems for $k$-snakes, studies their motion under the variation of a parameter, and presents a differential equation satisfied by the snakes. The results contain, as special cases, corresponding properties of constrained polynomials that deviate least from zero. Bibliography: 15 titles.
