We investigate the properties of heavy flavored baryon hypernuclei (i.e., , , and hypernuclei) within the framework of the relativistic mean-field model. It is found that no or bound states could exist if the potential well depth or in nuclear matter. If or , or cannot bind to the very heavy nuclei, for example . We suggest that it is not necessary to consider heavy systems in the experimental searches for and hypernuclei. Very small spin-orbit splittings for , and hypernuclei are also observed. For , however, it is nearly zero. We find that the positive charges of and play a very important role in and hypernuclei. It is indeed the heavier mass of the -baryon that makes its level space smaller.
