actually those are characteristics of the phylum chordata. Vertebrates are a subphylum, vertebrata. The distinguishing characteristics of phylum chordata are:
1. A dorsal hollow nerve chord (a bundle of nerves that runs along the back side of the animal as opposed to the ventral or belly side)
2. notochord (what becomes the vertebra in vertebrates but is simply a stiff but movable "rod" in other chordates)
3. pharyngeal slits (slits in the pharynx or throat, only present in many chordates in the embryonic stages)
4. endostyle or thyroid (vertebrates have a thyroid, all other chordates have an endostyle. they both do the same basic thing only a thyroid has some functions an endostyle does not)
5. post anal tail (exactly what it sounds like. obviously many chordates only have this in the embryonic stages as well. humans have one but grow out of it very early in gestation)
Defining characteristics of vertebrates are:
1. Vertebra! (obviously but more specifically the segmented vertebral column)
2. Splanchnocranium (for all intents and purposes, a skull of some sort).
3. Sensory organs to help with balance and head movement (in humans the canals of the inner ear)
4. extrinsic eye muscles for eye movement.
yeahh, ur welcome.

∙ 14y agoMammals, along with birds, are warm-blooded. Along with reptiles and birds, they are amniotes. Mammals are unique among vertebrates in that they have hair somewhere on their bodies, feed their young with milk, and give live birth (except for the five species of monotremes). Placental mammals (about 90% of mammals) are unique in that they nourish their young in a placenta before giving birth.

All vertebrates are chordates but not all chordates are vertebrates?
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.
Are vertebrates the largest group among the chordates?
Vertebrates are a subgroup of the chordates, meaning that all vertebrates are chordates, but not all chordates are vertebrates. Vertebrates are distinguished from other chordates by having backbones or spinal columns.All vertebrates have muscular systems that mostly consist of paired masses, as well as a central nervous system which is partly located inside the backbone (if one is present). The defining characteristic of a vertebrate is considered the backbone or spinal cord, a brain case, and an internal skeleton, but the latter is not true for lampreys, and the former is arguably present in some other chordates. Rather, all vertebrates are most easily distinguished from all other chordates by having a clearly identifiable head. Sensory organs--especially eyes--are concentrated at the foreend of the body, and there is pronounced cephalization.
Is chordates vertebrates?
Chordates are not vertebrates because although some vertebrates are chordates theres many reasons why chordates arent vertebrates.the first reason is because chordates consist of a notochord or a dorsal nerve.
