Consquences of a high oxygen world?

Other than allowing Big Creepy-Crawlies, what else might pop up in such a world?

Would a Giant Enemy Crab be able to exist, or does the higher oxygen level not effect their blood's in-efficient oxygen carrying methods?

Stuff Blows Up far more easily for starters.

How high is "high?" Earth's atmosphere is about 20% oxygen. However, high pressure oxygen is toxic.

Oh just in-general, not really sure on how high it would be (all is purely hypothetical anyways)

The Speculative Documentary Blue Moon is set on such a world.

Also, the Prehistoric Park episode Bug Hose.

Insect - like creatures that are resistant to the negative effects of high oxygen could grow to large sizes, but forest fires would be so common land vegetation would have to be highly adapted to survive.

Well, if humans were ever to occupy such a world, their skins would age in a considerably higher rate.

A planet with lots of oxygen would probably have a big concentration of plant life, as plants release oxygen in their process of photosynthesis, all that oxygen has to come from somewhere.

Given the large amount of vegetation and oxygen, wildfires would take on catastrophic levels, so smart settlers would probably move away from the forests to avoid such disasters from harming them (and to prevent the mosntruous forest dragonflies from eating them)

Correct me if I am wrong but more oxygen would mean more Ozone and more ozone woul mean less radiation to the surface.

@Fancolors

Such a world isn't in a sci-fi setting, but a fantasy one. All life-forms are native to the planet.

If you're using arthropod-like creatures, their size would still be limited by the mass of the exoskeleton. Oxygen would allow them to grow to, say, Carboniferous sizes, but there would still be a point where they couldn't get much bigger without sacrificing mobility.

You could have one that does that though. A Land-Barnicle or something.

Also, to support the plant matter, there would also have to be more carbon dioxide. Earth's Percenatage of C.D would be 5% or something if I remember, so about 10% maybe?

Also, I think the plants would be much like many plants in my native Death World of Australia. They would be relying on the fires to produce fresh soil, and having seeds that germinante only after the seedpods have been burnt.

I think there were other adaptaions too. Look it up.
