The alimentary canal is relatively short because frogs are carnivores. The digestive system of frogs is made up of two parts: The body cavity of frogs contains several organ systems such as:Įach of these systems has its own structures and functions. These features are not present in female frogs. They also have a special pad on their first digit of the forelimbs, which is used to grip onto the female during mating.Male frogs have sound-producing vocal sacs, which they use to make mating calls.Frogs exhibit sexual dimorphism, which means that males and females look different.The digits on their feet are webbed, which helps them to swim. The hind limbs have five digits, while the forelimbs have four digits.Their limbs are used for a variety of tasks, such as swimming, walking, leaping and burrowing. Frogs have four limbs - two at the front ( forelimbs) and two at the back ( hind limbs).On either side of the eyes, there is a membranous tympanum (ear) that receives sound.Above the frog's mouth, there are a pair of nostrils.This membrane helps to protect the eyes while the frog is underwater. Frogs have protruding eyes that are covered by a protective membrane called the nictitating membrane.This means that their head is directly connected to their body without a visible neck or tail Frogs are divided into a head and trunk.Instead, they absorb water through their skin. Unlike humans, frogs do not drink water through their mouths. On the ventral (lower) side, their skin is uniformly pale yellow. On the dorsal (upper) side of the body, frogs are generally olive green with dark, irregular spots. It's always kept moist to prevent it from drying out. The skin of a frog is smooth and slippery due to the presence of mucus. This is called summer sleep (aestivation) and winter sleep (hibernation), respectively. Frogs take shelter in deep burrows during peak summer and winter to protect themselves from extreme heat and cold. Frogs can change their colour to blend in with their surroundings and hide from predators. Their body temperature changes according to the environment. Frogs are cold-blooded or poikilothermic. Rana tigrina is the most common species of frog found in India. They can survive both on land and in freshwater. Frogs are members of the class Amphibia of phylum Chordata. ![]()
