Xenopus laevis, the African claw-toed frog, has been used in the laboratory by scientists for a long time. It has large embryos that can be easily altered by hand under a microscope, and so was a key organism in early experimental embryology. It was in Xenopus that the first successful clone was produced by nuclear transplantation by John Gurdon in 1958. You can get one of these mugs with the scientists' amphibian friend on it in our Kickstarter.
Green coloured mug featuring an illustration of Xenopus laevis and some facts about it.
