| Some jellyfish and turtles eat large quantities of ctenophores, and jellyfish may temporarily wipe out ctenophore populations. |
| It is therefore largely appreciated that the resemblance between ctenophores and cnidarians is superficial and does not reflect a particularly close evolutionary relationship. |
| At least two textbooks base their descriptions of ctenophores on the cydippid Pleurobrachia. |
| For a phylum with relatively few species, ctenophores have a wide range of body plans. |
| Data from sponges, ctenophores, and cnidarians are providing a glimpse into the some of the earliest events in Hox evolution. |
| In the cnidarians, chaetognaths, and ctenophores, the opaque gut wall was the surface measured. |
