  We demonstrate single-shot and \textit{in situ} absorption imaging of
individual Rydberg superatoms. This level of resolution is achieved using an
electromagnetically induced transparency scheme involving a Rydberg energy
level that is highly sensitive to the presence of Rydberg superatoms due to
F\"{o}rster-resonance-enhanced dipole couplings. Spectroscopic measurements
illustrate the existence of the F\"{o}rster resonance and underscore the
state-selectivity of the technique. With an imaging exposure time as short as 3
$\mu$s, we successfully resolve linear chains of Rydberg superatoms excited in
a one-dimensional configuration. The extracted second-order correlation shows
strong anti-bunching due to excitation blockade, and a Fourier analysis reveals
the long-range order in the chains of Rydberg superatoms. This imaging
technique, with minimal destruction, will be of great interest for leveraging
ensemble-encoded qubits in quantum computation and quantum simulation
applications.
