Question

Amphibians do not have exoskeleton. Give reason​

Answer 1

Answer:

Amphibians are a group of vertebrate animals that were the first vertebrates to leave the water and live on land. However, they did not develop the ability to live on land for their entire lives. Instead, they are born in the water and develop the ability to live on land as adults through a process of metamorphosis.

Answer and Explanation:

The most simple answer to why amphibians do not have exoskeletons is because they did not evolve from the same ancestors as the arthropods. However, amphibians do not need exoskeletons because they are vertebrate animals who evolved endoskeletons make of a series of internal bones. Additionally, amphibians need their permeable layer of skin to absorb their needed oxygen and water from the environment.

Answer 2

Amphibians do not have exoskeleton because vertibrates possess endoskeleton

Explanation:

• Amphibians are vertebrates, and vertebrates do not posses exoskeleton.
• Vertebrates possess endoskeleton, which serves the process of protection.
• As amphibians posses endoskeleton, they do not require exoskeleton for their protection.
• The endoskeleton consists of hard parts present inside the body.
• The exoskeleton consists of hard parts present on the surface of the body.
• Amphibians do not show the presence of an exoskeleton.
