Living Gears Help This Bug Jump
Planthoppers are champion jumpers - launching themselves upward, hundreds of times their own height, in just a couple milliseconds. They achieve this feat with the help of cog-like teeth on their legs — the first mechanical gear system ever found in nature.

How To Build Little Doors Inside Your Shell: The Secrets of Snail Carpentry
Snails getting ready for winter are natural carpenters. They construct doors, or maybe you'd call them walls, inside their shells. They do this without hammers, nails or cement. Instead, they use their foot — and of course, their favorite material, mucus. Welcome to the ingenious world of snail construction.

Parasitic Bird Fights Evolutionary Arms Race… With Itself
In the image above, all the eggs in the top row are laid by cuckoos and those in the bottom row belong to their victims. These uncanny similarities help cuckoos to fob off their parental duties by laying their eggs in the nests of other species. If the hosts can’t tell the difference between their eggs and the foreign ones, they’ll end up raising the cuckoo chick as their own. And they pay a hefty price for their gullibility, since cuckoo chicks often kill or outcompete their foster siblings.
