Frog Fathers Leave Their Tadpoles In Cannibal-infested Pools
2014-01-22 10:33:10

Springer Male dyeing poison frogs make seemingly strange parental decisions in depositing tadpoles in not-so-safe havens Given a choice, male dyeing poison frogs snub empty pools in favor of ones in which their tiny tadpoles have to metamorphose into frogs in the company of larger, carnivorous ones of the same species. The frog fathers only choose to deposit their developing young in unoccupied pools when others are already filled with tadpoles of a similar size as their own. These are...

Female Lovelorn Frogs Grab The Closest Male

BioMed Central What lures a lady frog to her lover? Good looks, the sound of his voice, the size of his pad or none of the above? After weighing up their options, female strawberry poison frogs (Oophaga pumilio) bag the closest crooner they can, finds research in BioMed Central's open access journal Frontiers of Zoology. This seemingly short-sighted strategy turns out to be the optimal mate choice strategy for these colorful frogs. Males of the species congregate in the Costa Rican rain...

Predators Drive Evolution Of Poison Dart Frogs' Skin Patterns
2011-11-22 04:10:01

Natural selection has played a role in the development of the many skins patterns of the tiny Ranitomeya imitator poison dart frog, according to a study that will be published in an upcoming edition of American Naturalist by University of Montreal biologist Mathieu Chouteau. The researcher's methodology was rather unusual: on three occasions over three days, at two different sites, Chouteau investigated the number of attacks that had been made on fake frogs, by counting how many times that...

Researchers in China have discovered the first protein-based toxin in an amphibian "“a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison.While gene-encoded protein toxins have been identified in many vertebrate animals, including fish, reptiles and mammals, none have yet been found in amphibians or birds. In the case of poisonous amphibians, like the tropical poison...

QUITO, Ecuador -- Before the arrival of Spanish colonizers some 500 years ago, Indians in what is now Ecuador dipped their arrowheads in venom extracted from the phantasmal poison frog to doom their victims to convulsive death, scientists believe. More recently, epibatidine -- the chemical which paralyzed and killed the Indians' enemies -- has been isolated to produce a pain killer 200 times more powerful than morphine, but without that drug's addictive and toxic side effects....

2014-09-12 08:59:50

The Golfodulcean Poison Frog, Phyllobates Vittatus, is a species of frog belonging to the Dendrobatidae family that is native to Costa Rica. Its natural habitats are subtropical or tropical, moist, lowland forests and rivers. It’s threatened by habitat loss. Like all members of the genus Phyllobates, Golfodulcean Poison Frogs have highly potent neurotoxin alkaloid poisons in their skin. While it’s only the fourth most toxic of the genus, the Golfodulcean Poison Frog is still a highly...

2014-09-12 08:52:55

The Strawberry Poison-Dart Frog, Oophaga Pumilio or Dendrobates Pumilio, is a species of small amphibian poison dart frog located in Central America. It’s common throughout its range, which stretches from eastern central Nicaragua through Costa Rica and northwestern Panama. The species is frequently found in humid lowlands and premontane forest, but populations of large size are also found in disturbed areas such as plantations. This frog is perhaps most famous for its widespread varieties...

The Golden Poison Frog, Phyllobates Terribilis, known also as the Golden Frog, Golden Poison Arrow Frog or the Golden Dart Frog, is a poison dart frog that is native to the Pacific coast of Colombia. The optimal habitat of this frog is the rainforest with high rain rates, altitudes between 100 and 200 meters, temperatures of at least 26 degrees Celsius, and relative humidity of 80 to 90 percent. While in the wild, this is a social animal, living in groups of up to six individuals; however,...

Ranitomeya Amazonica
2014-09-11 11:50:10

Ranitomeya Amazonica is a poison dart frog belonging to the genus Ranitomeya. It was initially described by Rainer Schulte in 1999 as Dendrobates Amazonicus when he separated it from Dendrobates ventrimaculatus. The validity of the species is still being discussed between scientists. According to Schulte, this frog is 16 to 19 millimeters long with smooth black skin. The torso is laterally striped orange or red while the legs and the arms have a mesh of blue, grey, or green on black. There...

Andinobates
2013-07-30 13:21:47

Andinobates is a genus of poison dart frogs located in South America. It contains species previously classified in the genus Dendrobates and in 2006 transferred to the genus Ranitomeya. In 2011, Twomey, Brown, et al. erected the genus called Andinobates for a group of twelve species of Ranitomeya. Andinobates frogs can be distinguished from their sister taxon Ranitomeya anatomically in that their second and third vertebrae are fused. They show no limb reticulation, which is present in the...
