The features distinguish chordates from other groups of animals are:
A) Single, hollow nerve cor beneath dorsal surface, in vertebrates, it differentiate into brain and spinal cord
B) Notochord, flexible rod on the dorsal side of gut present at one stage in all cordates, displaced in vertebrates by vertebral column that forms around the nerve cord
C)Pharyngeal slits(pouches) connect pharynx(between mouth and esophagus)
D)Postanal tail extends beyond anus present at least in embryo

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 ant chordate or non-chordate?
Ants and all other insects are non-chordates. Insects belong to the subphylum arthropoda. Animals that are vertebrates are considered to be chordates.
Difference between chordates and vertebrates?
humans are vertebrates as hey have the vertebral column(to be more specific the notochord). u can feel your vertebral column by placing your hand on your back.the bony structure that seems to divide your back into two equal halves is nothing but your vertebral column.
All chordates are vertebrates?
Chordates include the vertebrates, or animals with backbones. However, not all chordates are vertebrates. Some chordates, such as the cephalochordates lack a spinal cord, and hence are not vertebrates. The term chordate does not refer to the spinal cord, but rather the notocord. This is a stiff but flexible rod that runs the length of an animal at some stage of its life, whether embryonic, or adult. Other essential chordate features include gills, tails, and a nerve cord. wish this helps... neon.crescent

Identify one similarity and one difference between vertebrates and other chordates?
They both have a notochord but a chordata does not have a back bone and the vertebrate does
What are characteristic of vertebrates that chordates do not have?
1. Notochord 2. A nerve cord 3. Slits in throat area yeahh, ur welcome. ---Yazzy (Username) 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.
Can chordates not have a notochord and still be what they are?
The presence of a notochord at some point in the organism's development is one of the characteristics that distinguishes chordates from other phyla. Without it, I'm not sure if the organism would be considered a chordate.
What are the characteristics tha distinguish echinoderms from other phyla?
their body plan
What two things are present in all vertebrates but not some chordates?
A distinct brain and gill slits used for respiration as opposed to filterfeeding. Granted, those last ones aren´t found outside the fish class, but other vertebrates still develop them in their embryology.
Why do vertebrates share a common ancestor?
Vertebrates share a common ancestor because they all descended from a single, ancestral species that had a backbone. Over time, this ancestral species diversified into the many different types of vertebrates we see today through the process of evolution and natural selection.
Is a sea turtle or a vertebrates?
A sea turtle is a vertebrate, just like any other turtle. Their spine is connected to the roof of the inside of their shell, which is why they can swap shells or get out of the ones they were born with, or it will kill it. No. The sea turtle belongs to the reptile group. Reptiles are chordates, also known as vertebrates. A vertebrate. After all, it has a spine.
