There are several specialisations in animation — 2D, 3D, character animation, sketching, modelling, rigging and so on. The coming years will see a big demand for character animators. Many 2D artists may cross ever to character animation because their expertise in 2D helps them understand character animation better. There are different shapes in animation — modeling, rigging, texturing, lighting and finally character animation. For example, rigging is like creating bones for a character, and to be good at rigging you need to know some nuances of anatomy too. A character animator knows a bit of rigging so that he can guide a rigging artist about the desired action and structure.
