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