Strange render, though in object mode I can see the object just fine I am having a strange issue where I could see well through camera in object mode, but when I am trying to render it, the result seems to be grainy color of the object but the actual object is not visible. The following is the view through camera:



after rendering the exact same frame.




Added the blender file. Yes, I have tried the camera settings and added additional lights into the scene, it is rendering on the final frames, but it is not rendering in the very first frame, the camera is set to follow a simple path.
Your scene is enclosed inside a giant cube that is disabled for the viewport ( and enabled for render (camera icon).



What you see is the inside of that cube that has a very dense value for volume scatter. To view the animal like object in your scene you can disable the renderability(camera icon) of the cube  on the outliner or bring down the volume scatter to a more reasonable level.
