Yes, lungfish possess jaws.
Lungfish, though possessing unique characteristics like the ability to breathe air, are still categorized as fish and retain the fundamental anatomical feature of jaws. These jaws are equipped with teeth, specifically adapted for crushing and grinding prey. The Ethiopian lungfish, Protopterus aethiopicus, exemplifies this, having rounded teeth on its upper jaw and crushing teeth on its lower jaw, which are used to break down food after it is sucked in.
