The crucifix toad (Notaden bennettii), also known as the holy cross frog, is a special type of frog found in Australia. It belongs to the Limnodynastidae family. This frog is known for its amazing ability to dig and live underground, which is why it's called a fossorial animal. It's also one of the few Australian frogs that uses bright colors to warn others, a defense strategy called aposematism. You can find this unique frog in western New South Wales and south-western Queensland.
The crucifix toad was first officially described in 1873 by a scientist named Albert Günther.

Meet the Crucifix Toad!
The crucifix toad is the most colorful frog in its group, the Notaden genus. While most frogs in this group are dark brown, the crucifix toad stands out with its many bright colors. Its back is a sunny yellow, with a striking cross pattern right in the middle. This cross is outlined with big black dots and filled with white, black, and red dots. Its belly is white, and its sides are blue.
This frog is small and very round. It has a blunt nose and small legs and feet. Because it spends a lot of time digging underground, its eardrum (called a tympanum) is hidden. Male crucifix toads can grow up to about 6.3 centimeters long, while females can reach about 6.8 centimeters. Their feet have small "spades" that help them dig deep into the soil.
Life in the Outback: Habitat and Survival
The crucifix toad lives on the ground in the dry, arid areas of western New South Wales and Queensland. To survive long dry periods, these clever frogs burrow deep into the earth. They stay underground, reducing their activity, until heavy rains arrive.
When there's a lot of rain, they emerge from their underground homes. They then start their breeding season in temporary ponds that form after the downpour.
Reproduction and Life Cycle
During breeding season, male crucifix toads call from inside the ponds to attract females. Their call sounds like a "woop." The tadpoles of this species grow very quickly. This fast development helps them make the most of the wet conditions and reduces the risk of the pond drying up before they can fully develop. Their entire life cycle, from egg to froglet, can be completed in as little as six weeks!
Amazing "Frog Glue"
When the crucifix toad feels threatened, it can produce a sticky, stretchy "frog glue" from its skin. Scientists are still studying all the uses for this special glue. It might help confuse and scare away predators, like snakes. It could also trap biting insects, which the frog might then eat when it sheds and consumes its skin.
Interestingly, male crucifix toads have been seen using this glue to attach themselves to the larger females during breeding. This glue is incredibly strong, even stronger than some non-toxic medical adhesives available today. It's a protein-based glue that works even when wet, making it a fascinating subject for ongoing research.
What's for Dinner?
The crucifix toad's main diet consists of ants and termites. These small insects provide all the energy this colorful frog needs to survive in its tough environment.
