Though tortoise lives on land as well as in water , it cannot be included in class Amphibia. |
| Answer» Solution :When tortoise LIVES on the land , it respires with the help of lungs. When in water, it puts out its nares (nasal opening) out of the water and brathes air. It cannot take up oxygen dissolved in water . In both the habitats it respires with the HELPOF lungs. Incase of true amphibians , this is not the case . They can breathe in water with the help of SKIN and on land with the help of lungs . Tortoise also has exoskeleton which is LACKING in AMPHIBIA. Therefore, tortoise cannot be included in class Amphibia. | |
