Daihua sanqiong is a possible ancestor of comb jellies. ^[2] It was a sessile relative to comb jellies. ^[3] It had combs with cilia just like modern day comb jellies. ^[3]

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
