Amphibian Ark Exhibit Opened at Paignton Zoo

If you live in England or are visiting England this summer, you might want to hop over to the Paignton Zoo, which yesterday  launched  the Amphibian Ark exhibit, The event was hosted by actor and musician Anthony Head (the cool Rupert Giles in Buffy the Vampire Slayer).

Here’s some info from the zoo’s website (edited):

Amphibian Ark will be home to 14 amphibian species, including the blue poison dart frog, the phantasmal poison dart frog, and the Anderson’s axolotl. Staff have also been working with relatively common species to perfect husbandry routines and protocols before taking on endangered amphibians.

Mike Bungard, Curator of Lower Vertebrates and Invertebrates at Paignton Zoo Environmental Park, said: “I’m very pleased – the facilities are excellent. We have a large, flexible working space with on and off-show animal care areas, the capacity for high level bio-security and a state-of-the-art water treatment system. The water garden links the exotic amphibians indoors with the idea of domestic garden conservation.”

Out of 6,000 known amphibian species, 50% are threatened or endangered, compared to 10% of mammal species. Amphibians are affected by habitat loss, climate change, pollution, pesticides and the deadly chytrid fungus. Unstoppable and untreatable in the wild, the fungus can kill 80% of amphibians within months. The aim is to protect species from the fungus, possibly by taking animals from the wild and then reintroducing them when it is safe to do so.

It’s hoped that Amphibian Ark will inform and inspire visitors, breed rare species, and become an internationally recognised training facility for herpetologists. Staff have launched two field conservation projects in the last year in Tanzania and Trinidad.

The zoo is close to Torquay (in Devon), which is accessible by train, and from Torquay you can take a bus  to Paignton.

The Amphibian Avenger – Lucy Cooke

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.

Frogs: A Chorus of Colors

On Sunday Susan and I ventured into New York City to see Frogs: A Chorus of Colors at the American Museum of Natural History, a traveling exhibit from Clyde Peeling’s Reptiland. The exhibit features over 200 live frogs in recreated natural habitats, complete with rock ledges, live plants, and waterfalls.

If you live near NYC or need an excuse to visit the Big Apple, I highly recommend this exhibit. Most of the exhibits are eye level for even the youngest kids, who had fun trying to spot the well-camouflaged frogs. They can also push buttons to hear frog calls and view videos of frogs in action.

Here are a few things we learned:

  • The Cuban tree frog is probably the smallest frog at only 1/2 inch in length
  • The cane toad lays 35,000 eggs in a single string
  • The Australian water-holding frog digs in desert soils and can remain underground for years
  • The world’s biggest frog is the West African goliath at 15 inches and weighing 7 lbs, as much as a newborn infant.

We saw a leaf mimic frog, whose head resembles a curving brown leaf to help it hide in the leaves. We saw other frogs that blended in perfectly with the moss, rocks, and bark. We watched one miniature frog, about the size of a fingernail, leaping from leaf to leaf, finally leaping and sticking on the glass right in front of Susan’s nose.

The stars of the exhibit were the poison dart frogs. Their blue, yellow, and green jewel-like colors warn predators not to eat them. One type of poison dart frog can kill 20,000 mice or 10 people with its poison, which is excreted through the skin. As the label on this exhibit says, “Don’t kiss these frogs!”
