DESCRIPTION:We compute the screening length for heavy mesons moving throug
 h an anisotropic\, strongly coupled N=4 super Yang-Mills plasma by means o
 f its gravity dual. We present the results for arbitrary velocities and or
 ientations of the mesons\, as well as for arbitrary values of the anisotro
 py. For generic motion we find that: (i) mesons dissociate above a certain
  critical value of the anisotropy\, even at zero temperature\; (ii) there 
 is a limiting velocity for mesons in the plasma\, even at zero temperature
 \; (iii) in the ultra-relativistic limit  the screening length scales as $
 (1-v^2)^{\\epsilon}$ with $\\epsilon =1/2$\, in contrast with the isotropi
 c result $\\epsilon =1/4$.
