Step-by-step explanation:
They carry oxygen cylinders because they cannot breathe in the water as they have lungs but generally most of the aquatic animals breathe through their gills.

Hello,
When we go deep into the earth or sea,the oxygen level decreases. So,deep sea divers carry oxygen cylinders in their backs so as to receive oxygen. If they do not carry them,they do not get oxygen and there is a chance even to die. They must need oxygen to breathe and live..
