Question

What type of dentition is the characteristic of mammals?

• A. Homodont
• B. Polyphyodont
• C. Diphyodont
• D. Acrodont

Answer 1

Answer:

C. Diphyodont

Mammals are characterized by diphyodont dentition.

• Diphyodont: This term means having two successive sets of teeth, first the deciduous (milk) teeth and then the permanent teeth. This is a key characteristic of most mammals.

• Homodont: This refers to having teeth that are all of the same shape and size, which is common in fish and reptiles, but not in mammals (with a few exceptions like dolphins).

• Polyphyodont: This describes having teeth that are continuously replaced throughout life. This is characteristic of many vertebrates like sharks and crocodiles.

• Acrodont: This refers to teeth that are attached to the top surface of the jawbone, without sockets. This is seen in some amphibians and reptiles.
