Exotic nonlinear supersymmetry is characterized by supercharges to be higher order differential operators,
and thus has a nature of a hidden symmetry. We review some aspects of nonlinear supersymmetry and related
to it exotic supersymmetry and nonlinear superconformal symmetry. Examples of reflectionless, finite-gap
and perfectly invisible PT-symmetric zero-gap systems, as well as rational deformations of the quantum
harmonic oscillator and conformal mechanics, are considered, in which such symmetries are realized.
