The Amphibian Avenger – Lucy Cooke

Friday, April 2nd, 2010

We’re proud to feature guest blogger, Lucy Cooke, The Amphibian Avenger, who tells us about herself, what her mission is, and how we can all help.

I love frogs. I always have. As a small child I became fascinated by the miracle of metamorphosis, catching and studying tadpoles like a true proto frog geek. As an adult studying zoology at Oxford the astonishing diversity of amphibian life seemed to me to most eloquently illustrate the incredible adaptive power of evolution.

When I heard about the global amphibian crisis I was completely horrified and keen to do something about it. I discovered that most of my friends didn’t know that over a third of amphibians are going extinct or about the horrors of the Chytrid fungus. It made me aware of how little press amphibians get compared with birds and mammals so I decided that, as a writer and filmmaker, the best thing I could do would be to spread the word. So for the last few months I have been traveling around Latin America researching stories for a documentary on the crisis and writing a blog about my findings. I’ve been to some amazing places, met some inspirational characters, and discovered some truly awesome frogs. And it’s not over yet.

I started my trip by joining an expedition into the Patagonian wilderness with ZSL [Zoological Society of London] scientists to search for Darwin’s frog – the last of the gastric- or throat-brooding frogs left on the planet and the only species of animal (other than the seahorse) in which the male gets pregnant. After the eggs are fertilised the male gobbles them up and 8 weeks later he burps up baby frogs.

I was lucky enough to see and film a daddy Darwin’s frog carrying several tadpoles in his throat sack. It was one of the freakiest things I have ever seen – a mass of tadpoles wriggling in a frog’s belly – it looked like something out of the movie Alien. It gave me goose bumps to witness something so very special but sadly so very endangered. Darwin’s frog is threatened by habitat destruction and also the rampant spread of the Chytrid fungus. It would be a devastating loss to biodiversity for such an extraordinary animal to disappear off the planet.

Since then I have licked poison dart frogs in Colombia, visited infested frog farms in Uruguay and hunted mass murdering toads in Chile.

But probably the most shocking story I have come across is that of the endangered Lake Titicaca toad, also known as the aquatic scrotum frog after its exceedingly wrinkly appearance. This monster of the deep has become the key ingredient for Peruvian backstreet Viagra. In downtown Lima I filmed juice bars where they put this toad in a blender and then drink it. A fashion which is pushing this unique amphibian to the brink of extinction.

I’ve still got Panama and Costa Rica to go and will be posting from these two countries that have already been forced to brave the first wave of Chytrid. So if you like frogs then follow my blog – I think you’ll enjoy my adventure. Frogs need champions to help raise their profile and the necessary funds to save them. So, please spread the word amongst your non-frog loving friends – it’s written not just for frog geeks and they may well learn something new and start to care about the little green guys nearly as much as me.

Giant Salamander: Earth’s Largest Amphibian

Tuesday, February 9th, 2010

We confess to paying most of our attention in our posts on Frogs Are Green to the stars of the amphibian world—frogs—and not so much on other amphibians. So to make up for that, we’d like to introduce you to Earth’s largest amphibian—the giant salamander of China and Japan.

BB-Japanese-Giant-Salamander

This creature is considered a living fossil because it hasn’t changed much in 30 million years. To put things in perspective, 30 million years ago our ancestors were little primates hanging from trees. It would be millions of years before some of these primates descended from the trees, and millions of years after that before the first humans.

The giant salamander lives in mountain streams and lakes and can grow up to 6 feet long. It has four digits on its front legs and five digits on its back legs and is covered with a slimy protective mucous. It spends most of its time walking on the river bottom, though it can swim quickly. On land, its small legs won’t carry it and it must drag itself along.

Like many amphibians, the giant salamander is endangered due to habitat loss. Construction of dams converts their free-flowing stream habitats into standing water or dries them up completely. They are also vulnerable to water pollution from mining activity and farming throughout their range.

Other threats to their habitat includes deforestation around the streams. This exacerbates soil erosion and causes increased runoff and siltation of the streams, reducing water quality and making it difficult for the salamanders to get enough oxygen through their skin. In addition, the giant salamander is considered a delicacy and is also used in traditional Chinese medicine.*

On the BBC News site, Dr. Takeyoshi Tochimoto, director of the Hanzaki Institute near Hyogo in western Japan, gives a guided tour of this unusual creature. (“Hanzaki” is the local name for the giant salamander.) After watching this video, however, I have decided not to hug a giant salamander if I ever meet one. They have a very large mouth and several hundred small teeth on the top and bottom and can bite if angry, causing serious injury. Generally, however, this is a shy and secretive animal and is unfortunately relatively easy to catch.

Yasuni National Park, Ecuador: An Amphibian Eden

Tuesday, January 26th, 2010

Scientists have recently identified Yasuni National Park in Ecuador as one of the most biologically diverse places in South America, and perhaps on earth. As Shawn McCracken of Texas State University—San Marcos, recently said, “The 150 amphibian species throughout Yasuni is a world record for an area this size. There are more species of frogs and toads within Yasuni than are native to the United States and Canada combined.”

Unfortunately this Eden sits on oil reserves and is threatened by proposed oil development projects. McCracken and other scientists from Ecuador, the United States, and Europe have proposed a moratorium on new oil exploration until the effects of such projects can be explored.

Reading about this, we couldn’t help but think about the movie Avatar and the attempted destruction of the planet Pandora to mine unobtanium. Unfortunately, we humans aren’t as wise as the Na’vi—yet. Let’s hope that Ecuador will preserve this incredible pocket of biodiversity and not be so shortsighted as to destroy parts of it for oil.

Here is more information from Save the Frogs and the Environmental News Service.

A Frog’s Dream…Save Our Home

Sunday, December 20th, 2009

As the year ends, and before we take a short break for the holidays, we’d like to show you the new poster we’ve created to promote our cause. Proceeds from the sale of the poster will go toward amphibian conservation organizations and toward developing free and inexpensive educational materials for kids.

Poster designed by Susan Newman, Illustration © Sherry Neidigh

The poster is a unique collaboration between my partner Susan (who is a graphic designer when she isn’t saving frogs) and illustrator Sherry Neidigh. Sherry approached us after seeing our blog and offered to donate one of her illustrations for our use. We were thrilled to receive this exquisite illustration to promote our cause.

Susan played around with various ideas, but what struck her about this illustration was its dreamy quality. She came up with the text, “A Frog’s Dream….Save Our Home.” I think these words are perfect. That frog looks so content immersed in his pond, surrounded by dragonflies and lily pads.

A bit about Sherry:

Sherry has been drawing animals since she was 2 years old. She attended the Ringling School of Art and Design in Sarasota, Florida, and has worked for Hallmark Cards.

Sherry’s clients include the National Wildlife Federation (Your Big Backyard), Highlights for Children, Sylvan Dell Publishing, and NorthWord Publisher. She works in gouache, watercolor, colored pencils, airbrush, and pen and ink. Her latest book is Count Down to Fall by Fran Hawk, published by Sylvan Dell Publishers. Sherry lives in Simpsonville, South Carolina, outside of Greenville, with her two dogs, Harper and Bisbee. You can learn more about her by visiting her charming website.

Susan and I are so grateful for the use of Sherry’s beautiful illustration. We hope you love the poster as much as we do. Susan also designed a t-shirt with the illustration. Both are available in our store.

Happy Holidays!
