Question

crockdles dont exchange gases through their skins nor do they have organs . how do they manage underwater?

Answer 1

Dear student,

Crocodile do have organs.They shows an unique ability to adjust its oxygen consumption to enable it to dive for longer. Their heart directs the blood flow to only functional organs or areas and limits the supply to them only so reducing the extra demand for oxygen. Crocodile uses its lungs as a reserve air supply so when it dives quickly, the majority of air from its lungs expelled out and thus enabled a crocodile to remain underwater for longer duration. Also crocodilian blood is remarkable in its affinity for oxygen, carrying more in oxygen rich areas, and relating it more quickly in oxygen deprived areas.
