This group is intermediate between the Sperm Whales and the 
Dolphins. It is distinguished from the former chiefly by the very 
small number of teeth, usually not more than four developed in the 
lower jaw, these fitting into pits in the upper ; these teeth are mostly 
developed only in the male. Dorsal small, posterior; pectoral short, 
ovate, placed low, with five fingers enclosed in thick skin; snout 
more or less produced, the forehead rising abruptly in the adult. 
Genera 4; species about 10, mostly of the Southern seas.
