Xenopus laevis is the clawed toad/frog in the photograph (it’s actually a third genus and not strictly a frog or toad), bred in captivity since the 1920s for lab experiments. The icon is essentially a private joke – the expression “I hope your rabbit dies” originated as a straightforward insult, but later became associated in the USA with pregnancy testing, due to the early use of rabbits for this purpose and the mistaken belief that when injected with the urine of a pregnant woman, they proved the test positive by dying. They don’t die, but they were generally killed after the test because it was uneconomic to keep them long enough to use again. (Testing with rabbits never caught on in the UK because (a) it is less reliable than a similar and cheaper test using mice and (b) the research assistants at the Edinburgh lab where it was done didn’t like killing them). Subsequently a pregnancy test was developed that uses Xenopus. Its advantages were that it was quicker, cheaper, reliable and that the animals could easily be kept and used again. Hence Xenopus, unlike the rabbits, lived.

So now you know.
