The pair-distribution function and the static structure factor are computed for composite fermions. Clear and robust evidence for a (Formula presented) structure is seen in a range of filling factors in the vicinity of the half-filled Landau level. Surprisingly, it is found that filled Landau levels of composite fermions, i.e., incompressible fractional quantum Hall effect states, bear a stronger resemblance to a Fermi sea than do filled Landau levels of electrons.
