Zoos to the rescue of frog with no croak

The British and Irish Association of Zoos and Aquariums (BIAZA) has published the list of reptile and amphibian species benefiting from conservation efforts by zoos in the UK and Ireland.
They include the axolotl, a critically endangered amphibian which retains its tadpole-like appearance as an adult and has an extraordinary ability to regenerate limbs, and the golden mantella, a bright yellow frog which attracts a mate with clicks not croaks.
