The fungus is the cause of a lot of the massive die-offs we're seeing in recent years.

The smoking gun in all this is the fungus.

The fungus is knocking out species...It impedes the ability of their skin to absorb oxygen and just suffocates them. It's the equivalent of us ingesting a fungus that takes over our lungs.

In many cases, captive colonies will be our only short-term way of avoiding extinction.
