There is the similar approach used by the plesiosaurs and their like,
where a predator with an enormous body gets spotted easily by smaller
prey, and has the be as manouverable as smaller prey to catch them.

Difficult to do with a large body.

A large body with a long and flexible neck gets a smaller profile in the 
prey zone and a _much_ more manouverable appendage.  The body part can
cruise unnoticed below the school of fish while the head darts around

Some of the more environmentally aware dinosaurs were worried about the
consequences of an accident with the new Iridium enriched fusion reactor.
