Step 1: Vertebrates are animals which have a vertebral column.

Step 2: Features of vertebrates:

  • An internal skeleton (endoskeleton) made of bone or cartilage.
  • A closed circulatory system consisting of blood vessels.
  • A well-developed nervous system.
  • Kidneys (excretory organs).

Step 3: Vertebrates are divided into five main classes: fish, amphibians, reptiles, birds, and mammals.

Step 4: Table 2 - Classes of vertebrates (fish, amphibians, reptiles):

\hline Class & Main features & Example \\ \hline Fish & Bony fish have smooth, wet skin. Fins are used for balancing and locomotion. & Fish \\ \hline Amphibians & Skin moist or with mucus. Four limbs, first land animals. External fertilization. & Frog \\ \hline Reptiles & Dry skin with scales. Internal fertilization. Four limbs. & Lizard \\ \hline \end{array}$$ **The table classifies selected vertebrate classes with their key features and examples.**
