This is a short video of a clever octopus carrying a coconut that it can hide in should it ever feel threatened (previously: this much longer video from 2009 that shows an octopus fully enclosing itself in a coconut). Pretty clever, octopuses. But do you know what I would want to be carrying if I was an octopus running around at the bottom of the ocean trying to defend myself? "A speargun." Exactly. The best defense is a good offense -- shooting fireworks under my bed to scare all the monsters away before going to sleep taught me that.
Keep going for the video, then daydream you live in a pineapple under the sea.
Thanks to Afterglow, who shines at night, but only for a little while after the sun goes down like one of those solar-powered garden lights.
