We present a first morpho-kinematics analysis of the Intermediate MAss Galaxy Evolution Sequence (IMAGES) sample. This sample is the largest two-dimensional kinematics sample representative of intermediate mass galaxies at z˜0.6. A robust classification scheme has been developed to divide the sample into three distinct classes based on dynamical characteristics : (i) the rotating disk galaxies ; (ii) the perturbed rotators ; (iii) the complex kinematics. We find that 43% of the galaxies have complex kinematics, 25% have perturbed rotation and 32% are consistent with pure rotation. A morphological analysis was also carried out and compared with the kinematical one. We find a good agreement between morphology and kinematics as almost all the spirals have relaxed dynamics and complex kinematics can generally be explain by disturbed morphological features. As in the local universe, a correlation between morphology and kinematics of distant object can be derived.
