Give a scientific reason: Amphibia shows adaptation for terrestrial as well as aquatic life.

(N/A) $\rightarrow$ Amphibians are adapted to live in both aquatic and terrestrial habitats.
$\rightarrow$ Their skin is moist and devoid of scales,which acts as a major respiratory organ during cutaneous respiration in water.
$\rightarrow$ The hind limbs are often webbed,which facilitates efficient swimming in aquatic environments.
$\rightarrow$ Fertilization is external and occurs in water,and the larval stage (e.g.,tadpole) undergoes metamorphosis exclusively in water.
$\rightarrow$ These dual adaptations allow them to successfully exploit both water and land environments.
