In the dark of the ocean, some animals have evolved to use bioluminescence as a defense. In the animation above, an ostracod, one of the tiny crustaceans seen flitting near the top of the tank, has just been swallowed by a cardinal fish. When threatened, the ostracod ejects two chemicals, luciferin and luciferase, which, when combined, emit light. Because the glow would draw undesirable attention to the cardinal fish, it spits out the ostracod and the glowing liquid and flees. Check out the full video clip over at BBC News. Other crustaceans, including several species of shrimp, also spit out bioluminescent fluids defensively. (Image credit: BBC, source video; via @amyleerobinson)

this is kinda creepy tho

The story behind this painting is very interesting, though.  The artist’s mother was very sick, so the house was always filled a suffocating silence.  This painting depicts him wanting to scream, but having to be silent, hence the anguished expression.  In the whole painting you see figures in the background, one of which is his sister.
