It is named after the Dai people. The name means Dai flower.^[2]

In 2019, Daihua and other Cambrian forms were hypothesized to be stem-group ctenophores. This leads to the assertion that ctenophores evolved from immotile, suspensivorous forms, a lifestyle similar to that of polyps.^[4] Cladogram after Zhao et al., 2019:

	Crown Cnidaria Xianguangia Daihua Dinomischus Siphusauctum Galeactena Crown Ctenophora
