gut is in stomach and cavity is in outer region of stomach,
No ,they lack gut but possess gastrovascular cavity .
Echinoderms also have a spacious coelom (an open, fluid-filled body cavity lined with tissue), large gonads, and (usually) a complete gut.

Cnidarians have no gut in their body .The structure which performs function similar to gut is called gastrovascular cavity .
