Ironclad Beetle:
This beetle, native to Southern California, is renowned for its extreme crush resistance.
Exoskeleton:
The beetle's exoskeleton is remarkably tough, with interlocking plates that act like a jigsaw puzzle, distributing stress and preventing crushing.
Strength:
Studies have shown that the beetle can withstand forces approximately 39,000 times its body weight, according to Berkeley Lab News Center.
Adaptations:
The beetle's exoskeleton is an adaptation that evolved to protect it from predators and harsh desert conditions, according to Nature.
Elytra:
The beetle's elytra, or outer wings, are also fused together to provide additional protection, forming a crush-resistant shield.

Given a choice between two sea snail shells, hermit crabs know which will make a better home. That is, unless their thinking has been muddled by ingesting microplastics. Then, they struggle with a decision that could be crucial for survival.
They aren't alone: across the animal kingdom, it appears, tiny bits of plastic change behaviours and mess up cognition. Exposure to these particles makes mice more forgetful and less social. Bees have trouble learning. Zebrafish act more anxious.
