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:
