Solution

Crocodiles, birs, mammals have four-chambered heart.

Heart is usually three chambered in reptiles with an exception crocodiles, which possess four chambered heart. The division in their heart is due to the incomplete interventricular spectum in ventricles. Whereas, amphibians possess a three chambered heart in which the ventricl are not divided hence, 2 artia and one ventricle is present.
