The author gets his whales wrong. The giant anthropod was a filter feeder therefore the Blue Whale of the Ordovician.

[ Ancient arthropods were able to grow to ginormous sizes for two main reasons. First, oxygen was much more concentrated in the atmosphere 400 to 500 million years ago, making up 30% of Earth’s atmosphere instead of 21% today. Arthropods rely on air flowing through their bodies in order to take in oxygen; they don’t have lungs like us. The extra oxygen basically served as added fuel for growth. Second, and more simply, there weren’t really any larger predators around to cull their numbers. Call it evolutionary luck. ]
Concerning oceans the ocean speciaes arthropods have gill like structures.

Crustaceans, molluscs, and some aquatic insects have tufted gills or plate-like structures on the surfaces of their bodies.

They do as much damage to science as climatologists.

So what I am hearing then is that the 21% oxygen in our atmosphere is a good thing. Otherwise spiders will grow to enormous sizes.
