Frog teeth are not especially notable– in truth, a lot of individuals arent even aware that frogs have teeth. In Southeast Asia, an unique set of frogs display an intriguing adaptation: they possess two prominent bony protrusions, similar to fangs.
Quickly later on, the scientists began to find the little frogs. “Normally when were searching for frogs, were scanning the margins of stream banks or learning streams to identify them straight in the water. After repeatedly monitoring the nests though, the team began to find participating in frogs sitting on leaves hugging their little nests,” Frederick said.

Frederick and his group discovered nests of frog eggs on the leaves of tree saplings and moss-covered stones while trekking on the island. Frogs lay eggs that are encapsulated by jelly, instead of a hard shell. To keep them from drying, the majority of amphibians lay their eggs in water. In this case, the scientists discovered them raised above the forest floor.
The scientists called the brand-new species Limnonectes phyllofolia, with phyllofolia meaning “leaf-nester.” The finding shows the importance of conserving tropical environments like the one on the island of Sulawesi, which they argue has as much biodiversity as the Amazon. “Most of the animals that reside in places like Sulawesi are quite special, and habitat destruction is an ever-looming conservation problem,” Frederick said.
Working with the Bogor Zoology Museum and a team from the University of California, Berkeley, Frederick discovered the frogs on Sulawesi, a rugged, mountainous island that accounts for a large part of Indonesia. “Its a giant island with a huge network of mountains, volcanoes, lowland rain forest, and cloud forests up in the mountains,” Frederick said.
Preserving close contact with the eggs allows the frog moms and dads to coat them with compounds that keep them free and wet from bacterial and fungal contamination, the scientists said. A closer appearance at the moms and dads likewise showed that they were little members of the fanged frog family and that the frogs caring for the clutches of eggs were all male.
The research study was published in the journal PLoS ONE.

Frog teeth are not particularly notable– in fact, the majority of individuals arent even aware that frogs have teeth. In Southeast Asia, a distinct set of frogs show an interesting adjustment: they possess 2 popular bony protrusions, akin to fangs. Frederick and his team think that the unusual reproductive habits might be related to the smaller-than-usual fangs for the frogs size. Some of the frogs family members have larger fangs, which help them to keep away the competition for areas to lay their eggs in the water. As these frogs have progressed a method to lay their eggs above the ground, they might have lost the need for such huge fangs.
Jeff Frederick, a postdoctoral scientist at the Field Museum in Chicago and the research studys lead author, stated the new species is tiny compared to other fanged frogs on the island where it was found. “Many frogs in this genus are huge, weighing up to two pounds. This new species weighs about the very same as a cent,” he said in a news release.
Frederick and his group believe that the uncommon reproductive habits might be associated with the smaller-than-usual fangs for the frogs size. Some of the frogs loved ones have bigger fangs, which assist them to keep away the competitors for areas to lay their eggs in the water. As these frogs have progressed a method to lay their eggs above the ground, they may have lost the need for such huge fangs.
