Frog populations not helped by dinner menus

About one-third of all amphibians are listed as threatened species, with habitat loss the biggest factor.

But hunting is acknowledged as another important driver for some species, along with climate change, pollution and disease - notably the fungal condition chytridiomycosis which has brought rapid extinctions to some amphibians.

"Frogs legs are on the menu at school cafeterias in Europe, market stalls and dinner tables across Asia to high end restaurants throughout the world," said Corey Bradshaw from Adelaide University in Australia.

"Amphibians are already the most threatened animal group yet assessed because of disease, habitat loss and climate change - man's massive appetite for their legs is not helping."

Frogs are liquidised to make a "health drink" in parts of South America.

Frogs of the stream-dwelling Paa genus are among the most popular for hunting in China. But numbers in some areas have fallen 10-fold as a result of over-exploitation.

Rana chensinensis is declining steeply in some areas; a study in Heilongjiang found that the annual catch fell by 99% between 1971 and 1986. The main reason is traditional medicine.

Frogs and toads are also sold as tonics in the markets of Peru.

This stallholder in Cuzco sells "Extracto de Rana", a drink made from the extract of two to three frogs, which is blended with honey, malt and other ingredients.

Other recipes call for 30 frogs in a single drink. Image: Esteban Lavilla

In western Brazil and eastern Peru, frogs of the Phyllomedusa genus are used as a hallucinogen.

Chemicals secreted by the frog's skin and introduced into a human's bloodstream are said to lead initially to vomiting and incontinence, then deep sleep, and finally a period of enhanced sensitivity in sight and hearing. Image: E. Lavilla

Leptodactylus laticeps is exported from South America to the developed world. It can fetch prices of 600 euros in European pet shops.

In some areas where it lives, in Argentina, Bolivia and Paraguay, people earn as little as 1,200 euros in a single year, giving them a real incentive to catch and sell it. Image: E. Lavilla

Mantellas are among the most popular frogs as pets. The principal source is Madagascar, from where many amphibians are exported into the pet trade.

The hungry frog

We have a little koi pond in our back yard. One of our favorite amusements is our "froggie." We have watched him grow for the past several years. We were greatly surprised one day to visit the pond and find Froggie with a half swallowed sparrow protruding from his mouth. He caught a little more than he could eat.

The following are NOT my photos - but they tell the story very well ...

Crucified frog creates controversy

An ongoing row over a sculpture of a crucified frog on show in a Bolzano, Italy, museum gained momentum when a Catholic politician reported the work to the police for public obscenity.

The sculpture, which depicts a warty, pop-eyed amphibian nailed to a cross with a frothing mug of beer in one hand and an egg in the other, has been at the center of furious polemics ever since it went on display in May.

But the row has heated up after Pope Benedict XVI's arrival in the nearby town of Bressanone for his summer holiday.

Right-wing separatist party the Union for South Tyrol said Wednesday it had collected 10,000 signatures supporting the removal of the work, while the president of Trentino-Alto Adige regional council, Franz Pahl, entered his eighth day of a hunger strike in protest over the frog.

Local bishop Wilhelm Egger - a strong critic of the work from the start - said on Tuesday that he had discussed the sculpture with the pope, although he would not comment on the pontiff's views on the matter. "The crucified frog has shocked many visitors to the Museion and has hurt their religious feelings," Egger said.

Rare white albino tadpoles

Rare albino tadpoles have been found in a garden pond in Wales.

The tadpoles have the distinctive pink eyes and off-white skin coloration associated with albinism. Although isolated single examples of albino frogs, toads and newts have been seen before this is the first time a whole group has been found.

The pond's owner, who first noticed the white-tinged tadpoles, said he did not see any albino frogs using the pond during the breeding season.

Leap (frog) Day

What Are You Doing for Leap Day?

Starting February 29th more than 70 members of the Association of Zoos and Aquariums (AZA) will be celebrating "the Year of the Frog!" and holding fun, family-friendly events and programs to educate people about amphibian conservation.

Why Year of the Frog? One-third of all amphibians on the planet are threatened with extinction. Amphibian declines are now attributed to a new cause - chytridiomycosis - a disease that wipes out frogs, toads, and salamanders. Zoos and aquariums, with strong public support, will play a major role in preventing the amphibian extinction crisis - one of the most sweeping wildlife conservation challenges of our time.

I think in honor of the Year of the Frog, today, February 29th, should be known as Leapfrog Day!

Is that a frog I hear?

Advertisement calls are the loud calls that male frogs make to attract females. These are the familiar calls most people are familiar with. Some frog species have aggressive calls made by males towards other males, some have distress calls when bitten by a predator, and some have release calls.

Sample some frog sounds on this page.

Pylones Frog toaster

No! you don't toast frogs in it!

It's about time we let go of the boring conventions that confine us to mere function without beauty and joy. Loosen the ties of history, raise your toaster high and have friends over for pop tarts and waffles. This gem should be placed right in the center of the table.

Understanding Endangered Frog's Diet And Environment May Save It

A brightly colored tropical frog under threat of extinction is the focus of a new research project hoping to better understand how environment and diet influence its development and behavior.

Biologists from The University of Manchester have teamed up with experts at Chester Zoo in the hope that their findings will not only help save the splendid leaf frog Cruziohyla calcarifer from extinction in the wild but provide clues as to how it can be better catered for in zoos and aquariums.

Transparent Frogs

A research team led by professor Masayuki Sumida at Hiroshima University’s Institute for Amphibian Biology has created a type of transparent frog whose internal organs are visible through its skin. The researchers say the see-through frogs can help in the study of diseases and in the development of medical treatments by allowing laboratory scientists to check the status of internal organs and blood vessels while the frogs are alive and without having to dissect them.
