A kind of frog which was discovered in the month of November, 2021, has been named Assa wolumbin. These frogs are commonly referred to as pouch frogs or hip pocket frogs or marsupial frogs. These frogs are of the male parental care species type. This means that young people are being cared for by male frogs rather than females. Of the 4,000 species of frogs, only four exhibit this kind of behaviour. Here, males carry growing tadpoles in pouches thus taking care of them.
Description of Assa wollumbin
Assa wollumbin, the new frog species, is 2 cm long. Frog colors range from light cream to different shades of brown to brownish orange. There is a dark V-shaped mark on the back. The mark is between the eyes. The toes and fingers have webs. There is a small pad on the toe. This species of frog was previously believed to be the bag frog Assa darlingtonia. It was not classified as another species until the month of November 2021.
The population of Assa wolumbin is limited to only 2,000 hectares in the Wolumbin Mountains which is located in the warm subtropical rainforest of New South Wales in the country of Australia. These mountains are a sacred place for some indigenous communities.
It is a culturally and traditional important place for the people of the indigenous community named Bundjalung. This species meets state standards due to which it has been declared “endangered”. The frog population is so small that it is extremely vulnerable to the climate change.
Peculiar Breeding Biology
Female and Male frogs of this species mate under large stones or under litter on the floor of the forest. During mating, females lay several large eggs. These eggs are then laid on the ground. After that, the male frog remains with the eggs. It takes about 7 days for the eggs to hatch. When the egg is ready to hatch, the male frog puts itself on the egg. After the eggs have hatched, the male carries the tadpoles in a pouch. Young frogs grow up on these pouches. During the breeding season, males can mate multiple times and give birth to multiple young males at different stages of development.
