This weird behavior was observed by biologists from Harvard University in a species of frogs known as Trichobatrachus robustus and is manifested by a break in the bones in the toe pads, forming a new claw-like bone which then penetrates through living tissue, probably as a defense mechanism. David Blackburn from the ... |

It seems that the effect is not manifested only on populations, but on individuals as well. Many of the subtropical environments with high moisture levels have significantly different foliages, some being heavily covered with forests while others have almost no wood at all. Johanna Delgado-Acevedo and Carla Restrepo ... |

The noise of a waterfall can easily cover the croak of a frog and this is why, in most cases, many frogs living near flowing water have quiet croaks and lack vocal sacks. However, a Chinese frog came up with the perfect solution for this tiny predicament: ultrasound croaks! We're talking about the small concave-... |

So far, scientists have known about some salamanders (of the family Plethodontidae) and caecilians (worm-like amphibians) that had lost their lungs. Now they can add a frog on the list of lungless tetrapod vertebrates: the Kalimantan jungle toad (Barbourula kalimantanensis). This amphibian takes all the oxygen it ne... |

In tales, the princess must kiss a frog to turn it into the charming prince. In reality, this may not happen, but frogs have various uses around the world. We cannot say frogs are a stable component of the human diet, but in some countries people do eat frogs. Italians and French consider the frog legs a delicacy an... |

World's largest frog is the African Goliath frog (Conraua goliath) from central Africa: 13 in (33 cm) in body length (legs excluded), and weighs up to 7 lb (3 kg). But a newly discovered fossil frog from Madagascar dwarfed it: the armored amphibian had a body 16-inch (40 cm) long (and probably weighed around 5 ... |

There's nothing impressive in this Australian frog: dull coloration and just up to 5.5 cm (2.2 in) in length. But the Rheobatrachus frogs, first described in 1973, are nothing ordinary. Their name of gastric-brooding frogs speaks about an amazing breeding behavior in this species. While keeping them in an aquari... |

This top comprises animals you may have never heard about. EDGE (Evolutionarily Distinct and Globally Endangered) comprises animal species evolutionarily isolated. Most of them are extremely endangered (in fact, even their vulnerability makes the group or the sole species isolated from other lineages) and require rap... |

1.There are 5,250 species of frogs and toads. The name "frogs" and "toads" has no scientific basis. Usually, species with longer hind limbs, smooth and wetter skin and well developed foot webs for swimming are named frogs. "Toads" have bulkier bodies, often with warts, and shorter hind legs for crawling and hopping. ... |

Salamanders amaze us with their ability of regrowing limbs, but till we are able to do the same with our own limbs based on the salamanders' model, their relatives, the frogs, are on the way of delivering us a drug for correcting nasty facial scars. This would be the result of a team's research at Mancheste... |

Frogs can be pretty or not, but few people know that they can be extremely toxic. Most frogs you see are highly venomous (with one exception: the common frogs of the Rana genus). Like the cute little tree frogs. Still, they have their predators. Some snakes have 'a preference' for them, even venomous frogs,... |

This is the frog terminator: Batrachochytrium dendrobatidis, a fungus decimating complete populations of frogs and other amphibian species worldwide. The fungus kills off the frogs by clogging their skin and essentially asphyxiating them. By now it spread from Central America to Australia, Japan, Europe and the US. R... |

They may not produce eyes that have the color you prefer, but researchers have found a method of generating eyes starting with stem cells. At least eye tissues (like retina) could replace damaged parts in cataract, glaucoma, macular degeneration and other ocular conditions that impair vision, leading even to blindnes... |

This newly engineered amphibian could save thousands of frogs from massacre worldwide, no matter if for dissections in biology classes or medical research. A Japanese team succeeded in producing see-through frogs, so you can see their organs, blood vessels and eggs without the need of removing skin and muscles. "You ... |

1. A croak is produced by frogs by pushing air through the larynx in the throat. Most frogs have vocal sacs that amplify the sound. These are elastic skin membranes that work by distention. Tree frogs, toads and most South American and Australian frogs have just one vocal sack located under the throat (it can be larg... |

You fertilize a plantation to grow bigger and have more fruits, tubers, leaves and so on. But frogs around get "fertilized" too, developing horrific deformities. Nitrogen and phosphorus from fertilizers and animal waste leaking into lakes and ponds are the cause of this phenomenon. They boost the populations of a par... |

If you thought Brazil has the most diverse fauna in South America (and in the world), you're wrong: this title belongs to Colombia. This is also showed by the rhythm of newly discovered species in this country: now researchers have found a new poisonous frog in a remote mountainous region of Colombia. The new sp... |

This is the frog terminator: Batrachochytrium dendrobatidis, a fungus that is wiping out frogs and other amphibian species all over the world. Now researchers have found a secret weapon that enables the fungus to travel further and withstand harsh conditions longer, turning it more dangerous: sex. The fungus seems to... |

We could not say frogs are a stable component of the human diet, but in some countries people do eat frogs. Italians and French consider the frog legs a delicacy and in other European countries, you could also serve them as "slough chicken". In some areas of Latin America the frogs of the genus Leptodactylus are ex... |

Frogs are anything but intelligent; still, a synthetic version of a molecule coming from their eggs could save our big brains from cancer. The molecule called amphinase recognizes the sugary layer on the surface of tumor cell and binds to it before invading the cell and inactivating the RNA inside, killing the tumor.... |

You surely know Italians and French find a delicacy in the frog legs. You too may enjoy them. In some countries, dishes on frog legs are called "slough chicken". And southern Europe is not the only place where people consume frogs. In Latin America the frogs of the genus Leptodactylus are extremely appreciated and ca... |

Caribbean islands have sunshine and picturesque views. But they are in the end relatively isolated ones, with a rich fauna of frogs. DNA researches showed that at least 29 million years ago, South American frogs jumped on some kind of natural rafts, which carried them on until reaching either Central America or the C... |

Global warming hits hard on the amphibian species: a previously unknown fungal infection is decimating populations across the globe, with an extreme virulence in tropical America and Australia. Now a research points out that bacteria occurring naturally on the skin of some salamanders can slow down the deadly fungal ... |

Poison frogs are famous for their toxin which is used for poisoning arrow tips. Their bright vivid colors warn the predators on their toxicity. The toxins from the frog skin protecting it from predators and infections are chemicals called alkaloids. But frogs cannot synthesize the alkaloids themselves, they have to a... |

They should have named him Frogman, not Spiderman. Because the amazing ability to stick to smooth surfaces even when they are tilted well beyond the vertical is a trait displayed not particularly by spiders and insects, but also by many tree frogs and some lizards called geckos, even if by different methods. Some sm... |
