The Ctenophora and Cnidaria are radially symmetric and also have digestive chambers with one opening, which serves as both equally mouth and anus.
The collective worldwide geomorphic affect of animals to the procedures shaping the Earth's surface stays mostly understudied, with most scientific tests restricted to individual species and effectively-acknowledged exemplars.[sixty three]
