We've tried re-introducing them to the wild seven or eight times, but every time they die within a couple of years; if you don't get rid of the fungus, all you're doing is providing it with lunch.

Many species can't be bred in captivity,

We've been running a captive-breeding programme with the boreal toad ( Bufo boreas ) since 1995,

You can give them the right habitat and food, but they may need specific light or heat or moisture or group size, otherwise the female won't ovulate - and it can take years to study that.

I enjoyed about 25 minutes of that game. For that time we matched the intensity of the Florida Lady Gators. But at that time their energy stepped up - probably because of the mistakes we made - and they were consistent.

I've spent so much time working.
