The main features of vertebrata are:
1. Bilaterally symmetrical
2. Coelomic
3. Segmented
4. Complex differentiation of body tissues and organs
5. Notochord present
6. They possess a dorsal nerve chord
7. They are triploblastic
8. They have paired gill pouches
Vertebrates have a backbone made of individual bones called vertebrae, which house and protect the spinal cord. They also have a well-developed internal skeleton made of bone or cartilage, a closed circulatory system with a heart to pump blood, and a complex nervous system with a brain enclosed in a protective skull. Vertebrates also typically have paired appendages for movement, such as limbs or fins.

What are 2 main types of animals?
The two main types of animals are vertebrates, and invertebrates. This is classified as animals with a back bone (vertebrates), and animals without a back bone (invertebrates).
Why are the fossils of vertebrates similar to the bones of living vertebrates?
Fossils of vertebrates are similar to the bones of living vertebrates because they were once part of living organisms that shared similar anatomical structures and functions. Over time, the bones of vertebrates have undergone evolutionary changes, but many core features have been conserved due to their essential functions. This similarity allows paleontologists to make informed comparisons and infer the evolutionary relationships between ancient and modern vertebrates.
Is a horseshoe crab a vertebrate or invertebrate?
A horseshoe crab is an invertebrate. It lacks a backbone or spine, which are characteristic features of vertebrates.
What is the main function of a notochord?
The main function of a notochord is to provide structural support and flexibility to the body of an organism, particularly during development in vertebrates. It also serves as a basis for the development of the spinal column in vertebrates.
Why is the cephalochordates regarded as closely related to the vertebrates?
Cephalochordates are considered closely related to vertebrates because they share key characteristics, such as a notochord, dorsal nerve cord, and pharyngeal slits during their development. These shared features suggest a common evolutionary ancestor and a close evolutionary relationship between cephalochordates and vertebrates.
What are the main features of reptiles?
The main features of reptiles, according to the four most common means of categorising vertebrates are:they have scaly skin (not scales)as with other vertebrates, they breathe using lungs (as opposed to fish, which use gills)their young may be born live or hatched from eggsthey are cold-blooded

Main features of reptiles?
Reptiles are cold-blooded creatures. They commonly eat insects and have dry, scaly skin. They reproduce by laying eggs and all reptiles are vertebrates.
What anatomical features tells us humans are vertebrates and mammals?
First, our spines make us vertebrates. Giving live birth, and female milk glands are two features that make us mammals.

Do skunks have vertebraes?
Yes, skunks, like all mammals are vertebrates because they have backbones, one of the main characteristics of vertebrates
What is the defining feature of a vertebrate?
invertebrate has backbones and vertebrates has no backbone Animals can be classified into two main groups: Vertebratesand invertebrates. The main difference between vertebrates and invertebrates is that invertebrates do not have a backbone or a spinal column. Examples of vertebrates are birds and snakes while some invertebrates are insects and flatworms.
What is the main characteristic of all vertebrates?
They all have a backbone or spine.
