Adult fleas have what type of mouthparts?

• A. Sucking
• B. Piercing-sucking
• C. Chewing
• D. Sponging

Answer: (A)

Fleas feed on the blood of hosts using specialized mouthparts that both pierce the skin and draw blood. The mouthparts include needle-like stylets that penetrate the dermis and a feeding channel that suctions blood through. This combination—piercing the skin and then suctioning blood—is best described as piercing-sucking mouthparts. The saliva they inject helps prevent blood clotting and makes feeding easier. So, adult fleas are equipped for piercing-sucking feeding, not just a simple sucking, chewing, or sponging mechanism.
