All baryons eventually decay into protons, is this the same with anti-bayrons?

    (high school level physics btw)

    apparently all baryons eventually decay into protons, so I was just curious to know if this was also true of anti-baryons?

    The lightest anti-baryon is the antiproton, so any anti-baryon will eventually decay to an antiproton.

    Antiprotons are stable against decay (so far as we know), just like protons. However, sooner or later (probably sooner) an antiproton will encounter a proton and the two will annihilate:
