What is the difference between neutrinos and anti-neutrinos?

Given the properties of this leptons particles (mass, spin, charge) and the fact (not sure at all) that neutrinos and anti-neutrinos have no smaller constituents, I was wondering what are the differences between this particles.

When a neutrino interacts with something, you get a lepton out (e^-, μ^- or τ^-). When an antineutrino interacts with something, you get an anti-lepton out (e⁺, μ⁺ or τ⁺).

Afaik we can't rule out a Majorana neutrino experimentally, i.e. it could be that neutrino and anti-neutrino are identical.
