Dolphins (scientific name: Phallidae) have the typical morphological characteristics of toothed whales: spindle-shaped body; A crescent-shaped breathing hole; Skull intussusception, maxillary expansion backward and overlapping frontal bone; Left cranial top asymmetry; Tapered or spiked teeth, etc. The most obvious differences between species are related to feeding organs, such as beak, upper and lower jaws and teeth.

The length and size of beak and the number and size of teeth reflect the niche range occupied by different species. For example, the total number of teeth varies from about 10 (Richter dolphin) to 250 (dolphin). The appearance also varies widely. Only a few species, such as killer whales and pilot whales, are significantly type II, while more species can be slightly type II in body size, shape, color and dorsal fin shape.
