What are vertebrates What are their main features?
The main features of vertebrates are given as under:
- They possess a solid notochord.
- The body has bilateral symmetry.
- They have a true vertebral column.
- They have a dorsal hollow nerve cord.
- They are triploblastic.
- The terrestrial forms respire through lungs and the aquatic forms through gills.
- They are coelomate.
What makes vertebrates unique from other animals?
Vertebrates are more complex organisms when compared to invertebrates. The primary difference between the two is that vertebrates possess a backbone and an internal skeleton. In some vertebrates, the bones are replaced with cartilage, as seen in sharks.
What are Craniates and give their derived characteristics?
Characteristics. In the simplest sense, craniates are chordates with well-defined heads, thus excluding members of the chordate subphyla Tunicata (tunicates) and Cephalochordata (lancelets), but including Myxini, which have cartilaginous skulls and tooth-like structures composed of keratin.
What are the four characteristics of vertebrates?
As chordates, vertebrates have the same common features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail.
How can you classify vertebrates?
Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. Amphibians, reptiles, birds, and mammals are ranked as classes.
What are vertebrates and name their derived characteristics?
As chordates, vertebrates have the same common features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Vertebrates are further differentiated from chordates by their vertebral column, which forms when their notochord develops into the column of bony vertebrae separated by discs.
Why vertebrates are called craniates?
Hagfish are the only known living creatures with a skull but no vertebral column. Because of the presence of a skull or cranium, vertebrates are referred to as craniates. Craniata chordates include the more familiar chordates such as fishes, amphibians, reptiles, birds, and mammals.
What are the most important characteristics of a vertebrate?
The key characteristics of vertebrates include: vertebral column. well-developed head. distinct brain. paired sense organs. efficient respiratory system. muscular pharynx with slits and gills.

How are vertebrates classified from their common ancestor?
One of the ways life is classified is through the presence or absence of the vertebrate. Vertebrates and invertebrates evolved from a common ancestor that was speculated to have lived around 600 million years ago.
How are vertebrates classified in the animal kingdom?
“Vertebrates are animals that possess a vertebral column and/or notochord at any point in their lives.” One of the ways life is classified is through the presence or absence of the vertebrate. Vertebrates and invertebrates evolved from a common ancestor that was speculated to have lived around 600 million years ago.
