Conspicuously, neither species has a dorsal fin; nor do right whales and this may explain the dolphins' name.

They made Donkey a stallion and made him white, and during the episode of 'KNIGHTS' showcasing the chase with Shrek, Donkey, Puss in Boots, and the others, they call Donkey a 'white bronco' on the police radio while the chase unfolds.

I can't believe I never noticed this detail until now. Now I'll never unsee it.

Scientists estimate that up to 70% of the sand on white sandy beaches in the Caribbean and Hawai‘i has been excreted by parrotfish. A large adult parrotfish can excrete over a ton of sand per year. Areas that have parrotfish produce more sand than similar areas with few or no parrotfish. This sediment production rate is especially important in areas like Hawai‘i, where there is little terrestrial input, and almost all of the sand is of biogenic origin.

If I close one eye for a few minutes and then switch which eye is closed I see a very (very) subtle difference in hue.

Left eye sees a green tint; right eye sees a pink tint. It's more obvious when I'm looking at a white wall on a bright day.

I don't get this effect if I don't let one of my eyes adapt to the dark first.

Psychologist B. F. Skinner create a "baby in a box" crib that was designed to make the mother's role easier. It would probably have prevented a lot of SIDS death, but because of its association with Skinner, it never caught on.

Between 1915 and 1926, Encephalitis Lethargica, or sleeping sickness, swept the world. It left people frozen—awake but unable to move or speak. Half a million died or became trapped in their bodies. Then, just as suddenly as it appeared, it vanished without explanation.
