Vertebrates have several key characteristics including a highly developed brain, well-developed internal skeleton, advanced nervous system, sensory organs, ability to learn from mistakes, and ability to adapt to various habitats due to their skeletons and nervous systems. They also have respiratory systems using gills or lungs, protective skin, and bilateral symmetry. Birds are vertebrates that eat a protein-rich diet for flight energy, maintain body temperature through activity and warm blood, and reproduce through eggs with amniotic sacs and shells that hatch into chicks able to feed themselves.

2. GENERAL CHARACTERISTICS:
 They have a highly developed brain.
 They have a well-developed internal skeleton of cartilage and bone. So, vertebrates can develop bigger
bodies than invertebrates.

3. GENERAL CHARACTERISTIS:
 They have an advanced nervous system, more complex than that of invertebrates.
they have well-developed sensory organs
they can react very quickly to changes in their surroundings
these animals can learn from their mistakes

4. GENERAL CHARACTERISTIS:
 The highly developed nervous system and internal skeletons of vertebrates make them
adaptable to land, sea, and air. So they live in a variety of habitats.
 Most vertebrates can move and are heterotrophic.

5. GENERAL CHARACTERISTIS:
 They have a respiratory system with either gills or lungs.
 They have an outer covering of protective cellular skin.

6. GENERAL CHARACTERISTIS:
 They have a bilateral symmetry plan.
 Human beings are vertebrates, because they have a internal skeleton.

10. Their bodies
 Birds´ feet and legs are covered by thick
scales.
 Birds are covered of feathers and they
have wings to fly.
 They have also a horny beak.

11. Their food
 They must eat a high diet to get energy
for flying.
 They have light weight bodies and
strong muscles that help birds to fly.

12. Their temperature
 Birds can use heat from activity in their
cell to mantain the temperature.
 They have warm blood

13. Their reproduction
 Birds are oviparous their eggs have an
amniotic sac like reptiles and a shell.
 When bird chicks hatch they follow their
parents, they depend on a mother for
warmth and protection but they can walk
swim and feed themselves.
 They keep their eggs warm in a nest by
brooding.
