What is it about?
Experiments on dolphin and porpoise heads, in which pressure transducers were placed within the mouth, reveal that species with shorter, blunter heads and correspondingly rounder mouth openings generate stronger suction pressures within the mouth for better suction feeding.

Why is it important?
This work is important because it demonstrated, with experimental findings and mathematical analysis, that head and mouth shape are key determinants of water flow, which in turn help determine the effectiveness of feeding in cetaceans and other aquatic animals.
