  We introduce the concept of ``locality" for the strange sea in the nucleon,
which measures proximity of the strange and anti-strange quarks in the momentum
and coordinate spaces. The CCFR data for the strange and anti-strange
distributions imply a ``local" strange sea in the momentum space, which is
unexpected in QCD and is at variance with the simple meson-cloud model where
the strangeness is generated from the virtual transition of the nucleon to a
hyperon plus a kaon. We present a simple model to interpret the CCFR data and
to correlate momentum and coordinate space locality, yielding an upper bound of
0.005 fm$^2$ on the strange radius. We also discuss significances of locality
for other charge-conjugation-odd observables.
