Fire Resistant Fauna

This question is connected to: Fire Resistant Flora

I've been pondering a short story concept where a scientific expedition discovered a planet with a huge amount of both free hydrogen and oxygen in the atmosphere.

This is caused by an unobtanium crystal widespread on the surface of the planet which acts as a catalyst, splitting water into hydrogen and oxygen and absorbing heat and sunlight to do so. (That heat then gets released back into the environment when the gases burn).

The resulting atmosphere is highly flammable and as a result flash-fires are a common occurrence. These involve a burst of heat and flame and even mild explosions but are also over very quickly. Very fast-moving flame fronts sweep through the atmosphere, averaging at least one a day, but passing in a matter of moments. Water falls out of the sky in the aftermath of the flash fire and is then split back into oxygen and hydrogen once more by the unobtanium crystals.

Assuming animal life has evolved to survive in these conditions what adaptions could they make to survive?
