The two statements that are correct regarding what Cnidarians have in common are:
- They all have stinging cells.
- They all have radial symmetry.
Cnidarians, which include jellyfish, corals, and sea anemones, possess specialized cells called cnidocytes that contain stinging structures known as nematocysts. Additionally, Cnidarians display radial symmetry, meaning their body parts are arranged around a central axis.
