The species is highly distinctive due to the extremely long symphysis on the lower jaw, reaching lengths of 85 centimeters, while that of a modern porpoise is 1–2 centimeters long. The main hypothesis regarding its use is that it probed along the sediment in the murky estuaries and shores of what is now California in search of food, which would easily be scooped up the symphysis and into the jaws. The etymology of the name means "half beak", referring to the upper jaw being half the length of the lower. Additional Details Chitubox file provided if you want to resize the model.
