Amphibians are the first tetrapods to invade the land. The juvenile phase of the life cycle is dependent on water, where gas exchange occurs through gills. Amphibians have aquatic larval life and terrestrial adult life. Respiration is by gills, lungs and skin. Their body is divisible into head and trunk and skin is moist without scales. The two pairs of limbs are used for locomotion except for caecilians. They are cold blooded animals. Respiration is by gills (in larva), lungs and skin (in adults). Amphibians have a three-chambered heart. Fertilisation is external. However, in Salamander and Ichthyophis fertilization is internal. They are mostly oviparous, except for Salamander, which is viviparous. Development is indirect.

Explanation:

Frog Croaking:
Croaking of a frog is a form of communication and is primarily a sex call for females.

Communication:
- Croaking is a way for male frogs to attract females for mating.
- The sounds produced during croaking can vary in pitch, volume, and duration, depending on the species of frog.

Reproductive Behavior:
- Male frogs use their vocal sacs to produce these calls, which can be heard over long distances.
- The croaking sound is a way for male frogs to advertise their presence and availability to potential mates.

Mating Rituals:
- Female frogs are attracted to the calls of males and will choose a mate based on the quality of the call.
- The croaking of frogs is essential for successful mating and reproduction in many amphibian species.

Conclusion:
In conclusion, the croaking of a frog serves as a sex call for females during the mating season. It is an important form of communication and reproductive behavior in amphibians.
