Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE BEAVER AND HIS TESTICLES
There is an animal whose name in English is 'beaver' (although those garrulous
Greeks -- so proud of their endless supply of words! -- call him castor, which
is also the name of a god). It is said that when the beaver is being chased
by dogs and realizes that he cannot outrun them, he bites off his testicles,
since he knows that this is what he is hunted for. I suppose there is some kind
of superhuman understanding that prompts the beaver to act this way, for as
soon as the hunter lays his hands on that magical medicine, he abandons the
chase and calls off his dogs.
If only people would take the same approach and agree to be deprived of
their possessions in order to live lives free from danger; no one, after all,
would set a trap for someone already stripped to the skin.

You can find a compilation of Perry's index to the Aesopica in the gigantic appendix to his
edition of Babrius and Phaedrus for the Loeb Classical Library
(Harvard University Press: Cambridge, 1965). This book is an absolute must for anyone interested
in the Aesopic fable tradition. Invaluable.
