  Sea quark contents of the octet baryons are investigated by employing an
extended chiral constituent quark approach, which embodies higher Fock
five-quark components in the baryons wave-functions. The well-known flavor
asymmetry of the nucleon sea $\bar{d}-\bar{u}$, is used as input to predict the
probabilities of $\bar{u}$, $\bar{d}$ and $\bar{s}$ in the nucleon, $\Lambda$,
$\Sigma$ and $\Xi$ baryons, due to the intrinsic five-quark components in the
baryons wave functions.
