invertebrates or non-chordates
Invertebrates are animals without a backbone. Some types of invertebrates are worms, sponges, jellyfish and spiders.
No they are vertebrates and chordates.
Vertebrates (like humans) have a backbone. Invertebrates (like worms) lack a backbone.
Some of these non-chordates are marine animals. These animals are without a backbone. Some of these animals are... Fish Coral Sea-Aneamone
The opposite of chordata is invertebrates. Invertebrates are animals without a backbone, whereas chordates are animals with a notochord or vertebral column.
Notochord
phyllum chordata includes organisms which are both vertebrates and invertebrates. thus, we can say that all vertebrates can be chordates but all chordates cannot be vertebrates.
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.
Echinoderms are marine animals that are invertebrates, while Chordates are animals with backbones. Hope this helps!
The only vertebrate phylum is Chordata. All animals with backbones, or any bones at all, are chordates. Tunicates, which are filter feeding invertebrates with a spinal nerve but no bones, are also chordates.
