Personally, I like the idea, and the concept of these creatures miraculously surviving extinction events. The testing logs did feel a bit run-of-the-mill, but they weren't badly done.
I do wish that the image was at the top. If you do describe it so well, why not have a visual in your head of the creature while you read the article? Just a thought.
I think what I wanted the most is an extension/expansion of the current logs at the end of the article. It felt a bit short, and I didn't feel as if it hit the marks I wanted it to. (Length and emotion are the two big ones)
Imagine being trapped in what is essentially a death box surrounded by something you can't see. That's terrifying. If possible, maybe expand the logs to give a harder punch?
I will say, you did a pretty good job at terminology and keeping tone consistent through the whole thing.
No-vote for now, may review for later.
