Question

what are vertebrates​

Answer 1

Answer:

Vertebrates:-

1. The sub-phylum vertebrata includes

animals which are bilaterally symmetrical, triploblastic, coelomic and segmented.

2 The animal body typically consists of four regions : head, neck, trunk and tail.

3. The notochord is replaced partly or fully by a jointed vertebral column (back bone) in the adult. The body of vertebrates is characterised by the presence of a well developed skeletal system that allows a special distribution of muscle attachment points to be used for movement.

4. Besides vertebral column and internal skeleton, the vertebrates have a well developed nervous system (brain) and sense organs (eyes, ears and nose).

5. The vertebrates have a complex differentiation of body tissues or organs.

6. There are two pairs of appendages (fins or limbs).

7.Respiration is by gills in lower aquatic vertebrates. Higher land forms have lungs for gaseous exchange.
