  The chaotic flow of elastic fluids at low Reynolds number (Re) is typically
distinguished into elasto-inertial and elastic turbulence (EIT/ET). However,
the clear separation among these two turbulent regimes in parallel flows with a
gradual Re decrease remains elusive. Here, spanning Re over four orders of
magnitude, we investigate the statistical and structural nature of the flows
computed by fully resolved 3D numerical simulations, revealing that as inertia
becomes sub-dominant all flows share similar dynamical properties. Supported by
the results, we thus propose a unified view of fully developed ET and EIT in
parallel flows.
