The frog has no neck which helps for
Respiration
Jumping on ground
Paddling in water
Catching prey
Correct Option
The frog does not contain a neck, and the head continues into the trunk without interruption. The frog rests on land using long hind limbs folded into a Z shape and its short forelimbs upright. The frog jumps by abruptly extending its hind limbs, which function as springs. The frog can jump better since it has no neck.
