Question

Which adaptation of the frog differentiates from the fish? Presence of mucous glands in the skin OR ability to live in water also?​

Answer 1

Answer is presence of mucous glands on skin, because the characteristic of amphibians is that on land they breath through lungs and in water through these mucous glands.

Answer 2

The answer is mucous glands, these enable the frog to leave the water and live an amphibious life on both land and in water. Fish do not need mucous glands as they don’t leave the water so don’t need to protect their skin from drying out. A frog cannot live solely in the water, they need to breathe air and would drown if they stayed in the water, fish need to stay in the water to survive.
