The dorsal nerve cord is one of the embryonic features unique to chordates, along with a notochord, a post-anal tail and pharyngeal slits. It is a hollow cord dorsal to the notochord. It is formed from a part of the ectoderm that rolls, forming the hollow tube, compared to other animal phyla, which have solid, ventral tubes. The dorsal nerve cord is later modified into the brain and spinal cord. Dorsal nerve cord is mainly found in phylum Vertebrata.
Dorsal means the "back" side, as opposed to the belly side (ventral).
in vertibrates it is the spinal cord. ventral means from the back.
A dorsal, hollow nerve cord.

Yes
Features are a hollow nerve cord in the dorsalside of the body; ... Larger sharks have been said to exist, but at the moment have not been documented
Chordates
A dorsol hollow nerve cord is a major phylum in the Kingdom Animalia. A chordate is characterized by the presence of a dorsal notochord at some stage of development.
Notochord, Postanal Tail, Pharyngeal Slits, Dorsal hollow nerve cord
Yes, dolphins have a dorsal nerve cord. The dorsal nerve cord is an embryonic feature unique to chordates. Is it hollow and most mammals have one.
Dorsal means pertaining to the back, so a dorsal nerve cord is essentially a spinal cord; it's the never cord in the back. It connects the brain to all of the body below the head.
Yes. Kangaroos, like humans, are vertebrates, which are a subset of chordates (having a dorsal nerve cord).
Yes.
Chordates are animals that comprise the vertebrates. The three structures that are present during their development are the notochord, a tubular nerve cord and gill slits leading into the pharynx.
