sponges are made up of individual cells. I dont know about colentrates. They just are what they are. sponges also don't move while coelenterates do.
Sponges are of the phylum porifera and are assymetrical invertebrates that have no true tissues due to a lack of cell specialization. Coelenterates are any of the phylum cnidariathat have radial symmetry and are invertebrates. Coelenterates include corals, sea anemones, jellyfish, and hydroids.
The term coelenterates is now out of date and has been replaced with two terms Cnidaria and Ctenophora. Animals covered by these terms are jellyfish sponges and coral like animals. So the water is where your most likely to find most of them.
Sponges smell of soap which is ok, also feeding mechanism is stupid, it's also very lazy. Just feed yourself or the animal yourself with the normal food.
Diploblastic is generally referred to as "having a body derived from only two embryonic cell layers (ectoderm and endoderm, but no mesoderm), as in sponges and coelenterates".
importance of coelenterates
yes for sponges
it came in touch by a great scientist named Dylan Hanson discovered them
Yes, coelenterates are invertebrates.
why are collar cells important in classifying sponges as animals
harmful effects of coelenterates
A coelenterates habitat is in the ocean and if it is not it lives somewhere
