What is the term that encompasses the fire coral, sea wasp, and sea anemones?

Explanation:
Cnidarians. These organisms share a simple body plan with radial symmetry, two tissue layers, and specialized stinging cells called cnidocytes that contain nematocysts used to capture prey. Fire coral (a hydrozoan), the sea wasp (a box jellyfish), and sea anemones all belong to this same phylum, which is why they’re grouped together under cnidarians. The term Coelenterates appears in older classifications as a broad label for this group, but the current, widely accepted name is cnidarians.
