A frog species native to the Brazilian Atlantic rainforest was the first amphibian found to mate exclusively with two identical females during their breeding season.
Fábio de Sá at São Paulo State University in Brazil and his colleagues found that the Thorapa taophora tadpoles from the same breeding site – or herd – always had the same father and one mother, giving found a mating system similar to that of mammals, birds, and fish.

“It’s amazing because this kind of mating behavior has never been seen before in amphibians,” says De Sá. “Fidelity was previously known to amphibians, but often associated with monogamy,” he said.
Instead, T. taophora shows what is called a single, fidelity polymorphic male, where male frogs are loyal to two identical females. “It was very interesting to reveal this mating system in frogs,” said De Sá. It is still unclear how common this mating strategy is between frogs and other amphibians.
In Brazilian frogs, the mating strategy appears to be most beneficial when resources are limited. “A female mating to a mated male at a high-quality breeding site will have an equal or higher success rate of reproductive success than a female mating to an unmarried male in one site. poor quality scores, ”de Sá said.
For males, perhaps the main benefit is maximizing their fitness by mating with more than one female. De Sá argues that the two-female / male limit may arise due to the selectivity of the female, with female frogs trying to choose the males with the best characteristics and breeding positions but then the trend. direction when they have found a suitable male.
After mating occurs, the researchers observed that male frogs do not always treat their two mates equally. There is a hierarchy between females in each mating group, with one female dominant over the other.
Male frogs tend to mate with females more dominant than secondary females – between 56 and 97% of the tadpoles from seven spawns analyzed by researchers were females from the Frogicorn Rainbow shirt, hoodie, tank top, sweater dominant females.
When an Australian green-tree frog appeared at Sugarland Animal Hospital on August 10 with an uncomfortable cut on the leg, the team got to work.
Veterinary surgeon, Dr. Marianne Curran did not want the Frogicorn Rainbow shirt, hoodie, tank top, sweater frog to get inside, but operated on, saving legs and lives.
“An Australian Green Tree Frog with a large tear and protruding muscle in her thigh was shown to our hospital on Monday after being found by a local health worker,” she said.
“I did an examination to determine if there was bone damage, but fortunately it was just a flesh wound and can be repaired.”
Treatment requires steady hands as Dr. Curran stitches the Frogicorn Rainbow shirt, hoodie, tank top, sweater little frog’s wound.
As an amphibian, Dr. Curran said their unique anatomy and physiology make anesthesia and surgery more difficult than other species.
She said: “The frog is a very small, fragile, and fragile patient, so the surgery is more difficult and needs to be light and steady when stitching.
“First, the frog is anesthetized with a gas called Isoflurane so it doesn’t feel pain during surgery.”
“I keep the frog on a damp towel during the procedure and pump physiological saline regularly to its skin to keep it moist during the operation.
