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....

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...

Adelphobates
2013-07-30 13:15:48

Adelphobates, a sister group to the Dendrobates and Oophaga genera, is a genus of poison dart frogs. Excitobates, the proposed genus, includes some of the members. The name adelphobates is from the Ancient Greek, adelphos meaning brother or twin and bates meaning walker or climber. "Brothers" refers to Charles W. Myers and John W. Daly which are two unrelated scientists directly involved with the studies of the species. All members of this genus have conspicuous and vibrant coloration...

Reticulated Poison Frog, Ranitomeya ventrimaculata
2013-07-30 11:04:30

The Reticulated Poison Frog (Ranitomeya ventrimaculata) known in French as dendrobate a ventre tachete, is a species of poison dart frog. It is endemic to South America, where it can be found in Brazil, Colombia, French Guiana, Peru, and Ecuador. It resides in tropical rainforests, in trees and occasionally on the ground. It's threatened by loss of habitat. This frog secretes poison through glands within the skin which protect it from fungi and bacteria as well as from predators, which are...

Red-backed Poison Frog, Ranitomeya reticulata
2013-07-30 10:57:12

The Red backed Poison Frog (Ranitomeya reticulata) is a species of frog belonging to the family Dendrobatidae. It's an arboreal insectivorous species, and is the second most poisonous species in the genus, after R. variabilis. Like many species of small poisonous frogs native to South America, it's grouped with the poison dart frogs, and is a moderately toxic species, containing poison that is capable of causing serious injury to humans, and death in animals such as chickens. This frog is...

Ranitomeya sirensis
2013-07-30 10:53:54

Ranitomeya sirensis is a species of poison dart frog that is native to Peru. It is widely known as the Sira Poison Dart Frog, or more popularly as R. lamasi. It is kept as a bet by herpetoculturists and is considered to be one of the more difficult poison dart frogs to keep due to its relative rarity and the fragile nature of its tadpoles. Like most Ranitomeya species, R. sirensis is a mildly toxic poison dart frog. Its skin secretes small amounts of pumiliotoxins which coat the frog and...
