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
No- they do not belong to the phylum Cnidarian. They belong to Molluska.
A cnidarian has an incomplete gut with just one opening. BTW Those who said that "How many openings does cnidaria have?" and "How many opening does an earthworm have" are the same question are idiots. An earthworm in an annelid, or a member of phylum Annelida. Cnidarians are in an entirely different and less developed phylum, that is, phylum Cnidaria. So there. STAY IN SCHOOL!
A jelly fish. Cnidarian's have a sting cell called a cnidnocyte which is the defining feature.
Cnidarian comes from the Greek/Turkish word "Cnidos" which means stinging nettle
