I'm not sure if this is a baby that will grow bigger or just an absurdly tiny lizard, but it's a powerful reminder that life exists on every possible scale.
This small light bulb blew a while ago. It's never going to cast light again but in its death, it took on some weird patterns on the inside of the bulb.

This elephant stepped on a land mine in Thailand, blowing away much of its front right leg. It'll be able to walk better after this massive prosthetic leg gets strapped on.
The owner of this hand notes that their left pinky finger turns completely white in cold weather. For their pinky's sake, I hope they wear gloves when it's chilly.
