Cnidarians capture plankton with their tentacles, which retract and bring the food towards their mouths. Shorter ribbon-like oral arms then help move the prey into their stomach cavity (called a coelenteron), where a layer of cells produce strong digestive enzymes that breaks down the unfortunate captive within a dozen or so minutes. This same layer of stomach cells (the endodermis) absorbs and diffuses the nutrients to the rest of the jellyfish. Undigested waste is expelled through the same opening that it entered, making it both a mouth and an anus.
Cnidarian
Yes, coral is a cnidarian.
On the field trip, I saw a "cnidarian"when we went on a submarine.**************************A jellyfish is a basic example of a cnidarian.
respiratory system is a cnidarian
Mechanical Digestion
Mechanical Digestion.
It is called a polyp. Some examples are sea anemones and hydras.

Mechanical digestion.
The type of digestion that chewing is referred to as is mechanical digestion.
The basic body symmetry of a cnidarian, especially a jellyfish, is radial, meaning that no matter how it is bisected along its central axis, its two halves will be mirror images of one another.
No- they do not belong to the phylum Cnidarian. They belong to Molluska.
