Whether there is a superluminal object existing in the real world is a mystery in modern physics. Recently, OPERA collaboration claims that they have observed superluminal neutrinos in their experiments. This leads to a rest mass paradox by combining the observational results from SN1987A, if one considers the neutrino as a tachyon. In this paper, we identify the neutrino as a tachyonic chameleon, whose mass depends not only on coordinate frame but also on the environment, in which the neutrino propagates without the need of violation of the Lorentz-invariance at a fundamental level. We have compared our results with these observations and made some predictions that can be tested in the near future. Also, we have clarified the concept of rest mass for subluminal and superluminal object.
