From corals to jellyfish, the most common method of sexual reproduction is broadcast fertilization. However, most species also use asexual cloning during early stages of their lives, cloning new polyps that become individuals of a colony, or differentiate into a colony of specialized, symbiotic polyps. Some polyps 'bud', or clone, themselves into free swimming medusae, before using sexual reproduction as an adult to propagate offspring .
And then some corals are hermaphrodites and some cubozoans actually copulate, sort of, wrapping their tentacles around each other and transferring gametes into the female gastrovascular cavity. Some jellyfish brood their offspring and others simply release gametes into the sea during an aggregation of adults. So the answer to your question is rather diverse and complicated.
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 jelly fish. Cnidarian's have a sting cell called a cnidnocyte which is the defining feature.
No it is not. :)
Cnidarian comes from the Greek/Turkish word "Cnidos" which means stinging nettle
The sea
no. they are cetaceans.
no :P
no
No. Rather, it belongs under Phylum Mollusca, and class Cephalopoda. A Cnidarian has nematodes and cnidocytes, which a cuttlefish does not have.
