Which of the following is not true amphibian animal?

Correct option is A

The correct answer is (a) Tortoise

Explanation:
• A tortoise is classified under the biological class Reptilia, not Amphibia.
• Reptiles like tortoises possess dry, scaly skin and lay amniotic eggs on land, distinguishing them fundamentally from amphibians.

Information Booster:
• True amphibians (like frogs and salamanders) typically lead a biphasic life: undergoing an aquatic larval stage with gills and transitioning to a terrestrial adult stage with lungs.
• Amphibians require moist environments as their skin must remain damp to assist in respiration.

Additional Knowledge:
Frog (Option b)
• Frogs are anuran amphibians characterized by a lack of a tail in the adult stage and powerful hind legs.
Toad (Option c)
• Toads are also true amphibians, closely related to frogs but distinguished by their drier, bumpier skin.
Salamander (Option d)
• Salamanders are tailed amphibians belonging to the order Urodela.
None of the above/More than one of the above (Option e)
• Incorrect, as tortoise definitively stands out as a non-amphibian.

So the correct answer is (a)
