Question

Teeth are absent in the jaws of

• A. Amphibians
• B. Fishes
• C. Birds
• D. Mammals

Answer 1

The correct option is C Birds

• Birds, also known as Aves, are a group of endothermic vertebrates, characterized by feathers, toothless beaked jaws, the laying of hard-shelled l eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.
• Birds do not have teeth because the teeth and the jaw bone to support them are too heavy for efficient flight.
• Hence teeth are absent in the jaws of birds.
• So, the correct answer is 'Birds'.
