proper question: What are cilia used for?
disfluent question: What are ctenophores used for or I guess cilia?
context: Ranging from about 1 millimeter (0.039 in) to 1.5 meters (4.9 ft) in size, ctenophores are the largest non-colonial animals that use cilia (hairs) as their main method of locomotion. Most species have eight strips, called comb rows, that run the length of their bodies and bear comb-like bands of cilia, called ctenes, stacked along the comb rows so that when the cilia beat, those of each comb touch the comb below. The name ctenophora means comb-bearing, from the Greek (stem-form -) meaning comb and the Greek suffix - meaning carrying.
