I'm new on this forum. I've bred amphibians for over 30 years and have a small part time business breeding and selling amphibians. Right now the only frogs I'm working with are orange Phyllobates terribilis and Pipa parva. I'm working with lots of salamanders. One of my bragging points is supplying c.b. ribbed newts to NASA for research. For several years they have done zero gravity work in outerspace with Pleuorodeles. This year my salamanders will stay on the ground and be spun at twice gravity in a 24 foot centrifuge.
(This part is fiction )> After they master stem cell growth and regeneration in newts they will apply that information to mammals. They will take some of my best brain cells and multiply them. When they shoot them back in my brain I will be brilliant!
I'm active on Dendroboard, Caudata.org, and post a lot on Kingsnake.com amphibian classifieds.
