Question

Write a short note on vertebrata

Answer 1

Answer:

• They have a true vertebral column and internal skeleton.

• It allows completely different distribution of muscle attachment points that help in movement.

• Their body is bilaterally symmetrical, triploblastic, coelomic and segmented.

• In these animals, complex differentiation of body

tissues and organs is present.

• They have a dorsal nerve cord and paired gill pouches.

Thus, vertebrates are considered the most advanced group of animals.
