The growling grass frog (Ranoidea raniformis) is a fascinating frog found in southeastern Australia. It's also known by other names like the southern bell frog or warty swamp frog. In Tasmania, people sometimes call it the green and gold frog. This amazing creature lives in places like South Australia, Victoria, and New South Wales. It has also made its way to New Zealand.

What Does This Frog Look Like?
The growling grass frog is a very large frog. It can grow up to 10 centimeters (about 4 inches) long! Its skin is a mix of bright green and bronze colors. You might also see dark brown bumps on its back. Its belly is a pale cream color, sometimes with a faint pattern. A light-colored stripe runs from its head down its sides. Its upper legs are a pretty blue-green.
This frog has small bumps all over its back. It looks a lot like the green and golden bell frog. But you can tell them apart by these bumps, a shorter call, and a slightly different head shape. These frogs also have a visible eardrum, called a tympanum, on the side of their head.
Tiny Tadpoles, Big Future
The tadpoles of the growling grass frog are also quite large. They can grow up to 9.5 centimeters (about 3.7 inches) long. These tadpoles often have a coppery color on their sides. Their backs can even have a shiny, iridescent green glow.
Life Cycle and Behavior
Where Do Growling Grass Frogs Live?
These frogs love to live near water. You can find them in large swamps, ponds, and lakes. They especially like places with lots of reeds. They live in woodlands, shrublands, and open areas, even near the coast.
The growling grass frog is a good climber. However, it usually stays hidden among thick reeds or in swampy grasslands. It hunts for food and enjoys basking in the sun during the day. These clever frogs are known to hunt other frogs by listening for their calls.
Sounds and Calls
The male growling grass frog makes a unique call. It sounds like a three-part moan: "craw-ork ar-ar." The sound starts high and then gets lower.
Reproduction and Young Frogs
During the spring and summer, which is their breeding season, male frogs develop special black, rough pads on their thumbs. These are called nuptial pads and help them hold onto the female during mating. If a female frog feels threatened, she can make a hissing sound.
Female frogs lay many eggs, sometimes thousands! The eggs are laid in a loose pile in the water. The tadpoles then hatch and spend about 12 weeks growing before they transform into young frogs.
Protecting These Amazing Frogs
Sadly, the number of growling grass frogs has decreased in many areas. They have even disappeared from some regions, like parts of the Australian Capital Territory. Efforts are being made to help them. For example, in areas like the River Murray, water is carefully managed and delivered to their breeding spots. This helps new frog populations grow. You can still find these frogs in suburban areas of Melbourne and Geelong.
Where Can You Find Them?
The growling grass frog is originally from southeastern Australia. You can find them in places like South Australia, Victoria, New South Wales, and Tasmania. In 1867, these frogs were brought to New Zealand. Since then, they have spread widely across both the North Island and South Island of New Zealand.
Growling Grass Frogs as Pets
Some people keep growling grass frogs as pets. In Australia, you need a special permit to keep one. This helps make sure these frogs are cared for properly.
