And various other wasps have heavy metals concentrated near the apex of their mandibles. There's also resilin, an elastic-like compound(?) that concentrates energy at certain parts of insect joins, used during jumping, or other fast movements.

Which wasps?

See references therein for metals numerous other orders of not just insects but arthropods.

"metal mandible Hymenoptera" as a search.

The article describes the microscopic plating but doesn't show it. Here's a picture! http://cdn.sci-news.com/images/enlarge8/image_9093_2e-Acromy... Source: http://www.sci-news.com/biology/acromyrmex-echinatior-biomin...

> never before seen in insects Is this surprising, considering that an estimated 86% of species on Earth and 91% of ocean species remain unidentified? https://journals.plos.org/plosbiology/article?id=10.1371/jou...

The article takes great pains to point out that Leaf-Cutter Ants are not an unknown species though, they're one of the most-studied species of ant.

I like how their experiment was literally pitting ants against each other.

I did this a lot as a child. Find some random insect (beetle, spider, earthworm), pop it into an ant colony and spend hours watching the ensuing battle.

Never thought of it as cruel, which is unsettling when I imagine what an alien species with superior intelligence might choose to do with us.

I don't know, properly made chainmail suit is bite and scratchproof. Might be able to wrestle the tiger into submission. Though the weight of the tiger is going to be a VERY HUGE issue. Give me a spear and I'll be willing though.

Chainmail is bite proof in that it will likely prevent the tiger's teeth from puncturing your skin, but a tiger's jaw is strong enough to snap almost any bone in your body through the chainmail, so it's ultimately not going to do you much good.

Many cats kill by crushing the throat, choking the prey. I doubt mail would stop that.

Wow, archive.is is aborting on non-standard user agents. What a horrible practice.

...and it blocks TOR requests with a legitimate web browser (Firefox on Android) with unsolvable captchas.

Thanks, cloudflare. Thanks.

Even wearing chain mail I doubt you'd have a chance much higher than zero against a full grown tiger.

I have seen footage of a tiger pushing down the head of a charging antelope with one paw.

Human has no chance wrestling an adult tiger.
