The first frogs in our facility: Sweet Success / Las Primeras Ranas en Nuestras Instalaciones: Dulce Exito

Once all of the environmental systems in our captive breeding facility checked out, we added our first group of frogs.  Somewhat surprisingly, the frogs immediately began enacting reproductive behavior.  We had calling and a bit of dancing around between males and females.  We are happy to report that we already have at least one male frog holding developing young in his vocal sac!

Una vez que se revisaron todos los sistemas ambientales en nuestras instalaciones de cría en cautiverio, agregamos nuestro primer grupo de ranas.  Sorprendentemente, las ranas inmediatamente comenzaron a realizar un comportamiento reproductivo.  Tuvimos llamadas y un poco de baile entre hombres y mujeres.  ¡Estamos felices de informar que ya tenemos al menos una rana macho con crías en desarrollo en su saco vocal!
When we collected our first group of Darwin's Frogs from the field, we used a cooler to keep the frogs at an appropriate temperature during the trip back to Santiago.

This is the the female that we believe bred with our male. Her job is now done. Female frogs deposit eggs and the male frogs take over from there. Males attend the developing eggs before taking their young into their mouths and on into their vocal sac.

Las ranas hembras depositan huevos y los machos toman el relevo a partir de allí. Los machos asisten a los huevos en desarrollo antes de llevarse a las crías a la boca y al saco vocal.

    Congrats!! That is great news, and I can’t wait to hear about the froglets later.

    Hi,

    Our teacher had us visit your website after we talked about amphibian conservation in class. Seeing how a conservation project comes together this way has been great. Good luck in the future!

    Really, really, really good work!!

    Please keep it up.

    Are there any plans of sharing stock with other breeding facilities or zoos abroad, particularly from Europe?.

    How many different breeding lines do you intend to establish and how do you plan to cope with a possibly increased frequency of deleterious alleles?

    Is there any way to contact this project directly other than through this blog?

    Thanks.

    • Dear Gonzalo,

      Our goal is to produce captive bred frogs that are available for reintroduction efforts. Reintroductions are going to be the decision of the Chilean wildlife authorities. When we have breeding going at full tilt, we would be happy to consider a small number of animals for educational purposes.

      We hope to maintain at least three genetic lineages. Each of those lineages will ultimately include more than 50 individuals.

      Thanks for visiting the site and for your great questions!

    I’m very interested in Rhinoderma darwinii’s conservation. I’m currently studyng Biologia Ambiental and I’ve been reading a lot about this wonderful frog, thanks to professor A. Veloso who has borrowed me a lot of reading material
    Went to the zoo yesterday but it was impossible to see the frogs.

    I was wondering if by any chance I could go there again and meet someone who can tell me a little bit more about the work you’re doing, and maybe show me a frog so I can finally get to see one…

    Thanks in advance

    • Dear Matias,

      We have sent you an email and will arrange an opportunity for you to see our facilities and the frogs. Great to have the interest in Santiago for these incredible creatures!

      Cheers and Thanks

  7. I have had the honour of joining EDGE fellow Claudio Soto on an expedition to Southern Chile to look for a swab Darwin’s frogs last November. It was an unforgettable trip and I was lucky enough to see individuals with tadpoles in their vocal sacs. I am concerned about the spread of Chytrid and the effect it will have on wild populations of Darwin’s frog. I’m therefore delighted to see that you have already had success with captive breeding efforts. Congratulations! I want to ask you though what theory you have for this reproductive strategy. Both the fact that the eggs metamorphosis inside the throat sac but most interestingly why it is the male that has evolved to do this.

    Keep up the good work!

    • Hi Lucy,

      Great to see you have enjoyed meeting Darwin’s Frogs in situ. There is no question that these frogs are special. With regard to your question, we don’t have a hypothesis for the evolutionary pathway that led to the internal parental care observed in Rhinoderma. Vocal sacs in males are places where small offspring could be stored. Marsupial frogs and other species are known to harbor their young in and on their bodies, so the general approach has been independently evolved a number of times. The parental care provided is exceptional because a predator would have to be big enough to take an adult to threaten the babies. But the details behind how the parental care evolved are not clear. We guess the same question could have been asked for Australia’s gastric brooding frogs. It’s too bad they are gone; we could have learned so much from them at so many levels.

      Cheers and Thanks

    Wow, this is great news. I was hoping that an in-situ program for these frogs would get up and running before they disappeared forever. Keep up the good work.

    Glad I found your site and your project. Clearly important work here. At least somebody will preserve these animals from prosperity. BEst wishes and hopes for massive success!

    I can’t believe the baby frogs are even smaller than a finger! They are even cooler, too. I wish I had a club to join. Maybe you could start a kids club? But I learned about Darwin’s frogs in my science magazine, so that is pretty cool.
