  We used FORS2 in MXU mode to mimic a coarse 'IFU' in order to measure the 3D
large-scale kinematics around the central Hydra I cluster galaxy NGC 3311. Our
data show that the velocity dispersion field varies as a function of radius and
azimuthal angle and violates point symmetry. Also, the velocity field shows
similar dependence, hence the stellar halo of NGC 3311 is a dynamically young
structure. The kinematic irregularities coincide in position with a displaced
diffuse halo North-East of NGC 3311 and with tidal features of a group of
disrupting dwarf galaxies. This suggests that the superposition of different
velocity components is responsible for the kinematic substructure in the Hydra
I cluster core.
