Scientists discover seven new diamond frog species in Madagascar

Madagascar has earned a reputation as one of the world's greatest biodiversity hotspots, yet it continues to surprise scientists. A new study published in Vertebrate Zoology has identified seven previously unknown species of diamond frogs belonging to the genus Rhombophryne. The discovery brings the total number of recognised diamond frog species to 27 and offers fresh insight into how much of the island's wildlife remains undocumented.The finding is more than just another addition to the species list. It reshapes scientists' understanding of a group of frogs that has long puzzled researchers because many species are almost impossible to tell apart by appearance alone. By combining modern genetic tools with traditional anatomy, the team was able to uncover a level of diversity that had remained hidden for years.Frogs that look almost identicalDiamond frogs are not the colourful, eye-catching amphibians many people imagine.
