Daihua sanqiong is a possible ancestor of comb jellies.[1] It was a sessile relative ot comb jellies[2]. It had combs with cillia just like modern day comb jellies.[2]
It is named after the Dai people. The name means Dai flower.[1]
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.[3] Cladogram after Zhao et al., 2019:
