Chordates are animals that have a fluid filled body cavity with a complete peritoneum and there are two kinds Vertebrate and Invertebrate. Vertebrate Chordates have internal skeleton with a vertebral column. Invertebrate Chordates are a marine animal that lacks a vertebral column and are thought to have evolved from an extinct group of hemichordates. An example of a Invertebrate Chordates would be the Cephalochordata.
Some of them are.
Although the majority of animals that make up the phylum Chordata are vertebrates, some invertebrates are also part of this phylum. All animals which have a spine, or backbone, are classified in the phylum Chordata. There are three subphylums in Chordata: Urochordata (tunicates e.g. marine filter feeders such as sea squirts), Cephalachordata (lancelets e.g. sessile burrowing marine animals), and Vertebrata (vertebrates - mammals, birds, fish, reptiles and amphibians).
This phylum includes all animals which have a hollow nerve cord and a notochord at some stage during their development. In the case of vertebrates, the notochord is present in the embryo, and develops into the vertebral body.

Chordate pharyngeal slits appear to have functioned first as suspension-feeding devices.
Ants and all other insects are non-chordates. Insects belong to the subphylum arthropoda. Animals that are vertebrates are considered to be chordates.

I do not know to be honest, sorry.
Because it does not have a "back bone".
It is vertebrate Chordate.
No. A snake is a vertebrate.
No, it is an invertebrate or non-chordate
The body plan of an invertebrate Chordate is quite unique as it does not entail a backbone. It has a hollow dorsal nerve cord and post-anal tail among other crucial features.
The notochord of a vertebrate differs from that of an invertebrate because a vertebrates eventually turns into a back bone. Invertebrates just disappears.
They don't have a backbone and have all the characteristics of a chordate.
No, a narwhal isn't an invertebrate. Instead, it has a backbone. It belongs to the Chordate phylum, which has mostly vertebrate members. It also belongs to the class of Mammals, which all have backbones.
