Some of these non-chordates are marine animals. These animals are without a backbone. Some of these animals are... Fish Coral Sea-Aneamone
Notochord
Ants and all other insects are non-chordates. Insects belong to the subphylum arthropoda. Animals that are vertebrates are considered to be chordates.
Non-chordates are animals that do not possess a notochord, which is a flexible rod that provides support along the back of chordates (animals with a backbone). Non-chordates make up the majority of the animal kingdom and include groups such as arthropods (insects, spiders), mollusks (snails, clams), annelids (earthworms, leeches), and many others.
porifera & echinodermata
Yes, hemichordates are not chordates as they are their own phylum.
Notochord
no
Non-chordata is a zoological group that includes all animals excluding the chordates. These animals lack a notochord or backbone, which is a defining feature of chordates. Non-chordates belong to diverse phyla such as Arthropoda, Mollusca, and Annelida.
Ants and all other insects are non-chordates. Insects belong to the subphylum arthropoda. Animals that are vertebrates are considered to be chordates.
invertebrates or non-chordates
Yes, the ventral nerve cord is a character found in chordates, not non-chordates. It is a defining feature of chordates, running along the belly side of the body and often involved in coordinating motor functions.
Cephalochordates e.g. Amphioxus ,; tunicates , acorn worms etc. are nonvertebrate chordates , they are collctively called protochordates .

porifera & echinodermata
Star fish is an invertebrate. It comes under the phylum Echinodermata of non- Chordates.
There isn't a "popular name" for them. The most familiar chordates are the vertebrates, but not all chordates are vertebrates (tunicates, for example, are chordates).
all vertebrates are chordates because vertebrates are the sub- group of phylum chordates and also it follow one of the important feature of the chordates i.e. presence of notochord whereas all chordates are not vertebrates because some chordates are cephalochordates, urochordates.
