Australia is home to a unique group of small frogs commonly known as toadlets, along with the well-known but invasive cane toad. These amphibians vary widely in size, color, and habitat, ranging from tropical rainforests and wetlands to dry grasslands and desert regions. Despite their modest appearance, Australian toadlets play an important ecological role by controlling insect populations and contributing to healthy ecosystems.
1. Cane Toad
The cane toad is the most well-known toad in Australia and is considered one of the country’s most invasive species. Originally introduced to control agricultural pests, it spread rapidly across northern and eastern Australia, causing major ecological impacts on native wildlife.
Identification
- Large, heavy-bodied toad with dry, warty skin
- Color ranges from grey-brown to olive
- Prominent poison glands (parotoid glands) behind the eyes
- Adults commonly grow 10–15 cm long, sometimes larger
Habitat
Cane toads are highly adaptable and live in a wide range of environments, including wetlands, forests, grasslands, farmland, and urban areas. They are especially common near water sources such as ponds, drains, and creeks.
Diet
They are opportunistic feeders and eat insects, spiders, small reptiles, frogs, and even pet food. Their broad diet helps them survive in many different habitats.
Behavior
Cane toads are mostly nocturnal and are often seen at night under lights where insects gather. They secrete a powerful toxin that deters most predators, making them particularly dangerous to native animals unfamiliar with this defense.
Conservation Status
Cane toads are not protected in Australia and are actively managed due to their negative impact on ecosystems. They are listed as an invasive species rather than a threatened one.
2. Western Toadlet
The western toadlet is a small, ground-dwelling frog native to southwestern Australia. Unlike the invasive cane toad, this species is harmless and plays an important role in local ecosystems. It is well adapted to seasonal climates and is often active after rainfall.
Identification
