Description : Jerdon's bullfrog is a large and robust amphibian, with males growing up to 15 centimeters in length and females reaching up to 20 centimeters. Their skin is greenish-brown or olive-green in color and is covered in small warts. They have a distinctive fold of skin running down their backs that resembles a raised ridge. Jerdon's bullfrog has a broad, triangular head with large eyes. Their eyes are located on the top of their head, allowing them to see predators and prey in all directions.
The species has long, muscular hind legs that are adapted for jumping and swimming. Their hind feet are webbed, which helps them move efficiently through the water.
Jerdon's bullfrog can live up to 8 years in the wild.
The species is cold-blooded. They are most active when temperatures are warm and humid, and they may go to hibernation during colder months.
Jerdon's bullfrog is known for its loud and deep croaking call that can be heard up to a kilometer away. Males use this call to attract females during the breeding season, which typically occurs during the monsoon season from June to September. The species breeds in permanent water bodies, such as ponds, lakes, and slow-moving streams.
Jerdon's bullfrog is a voracious predator and feeds on a variety of insects, spiders, and other small invertebrates. They are also known to eat smaller frogs and tadpoles. The species is active at night and spends most of the day hiding in vegetation near water bodies.
Jerdon's bullfrog is currently listed as endangered due to habitat loss and degradation caused by human activities. It is important to raise awareness about this species and take measures to protect their habitat to ensure their longevity.
