Eye pearls are a lucrative but painful business.
Much like oysters, human eyeballs can grow pearls when given a small pebble or other solid irritant. The eye coats the irritant in a protective glaze that becomes a pearl like the one seen above. Valued at 50 times that of common pearls, eye pearls were highly sought in ancient times. The phrase “A twinkle in ones eye” derives from this practice, twinkus being latin for pearl.
Eye pearls are illegal now, as centuries of eye slavery was surely one of the most painful epochs of ancient times. But still, some intrepid and often masochistic individuals use their own eyes to grow this strange cash crop.
Extreme constriction under bright light.
Your pupils dilate (open) when its dark out to let more light in and constrict (close) when it’s bright out to close off light to the retina. When it’s super bright, they can close completely and under enough intensity, permanently. This is why you go blind if you look directly into the sun.
A bleached whale appears off the coast of Norway.
Marine biologists don’t fully understand why whales bleach themselves. Some think it’s because they get confused by submarine sonar, others think it may be suicidal behavior, and others suggest white supremacists are to blame. We may never know why, but there’s no question it happens and it’s been happening more and more.
It’s common for activists and passersby to try to help the whales but some suggest this does more harm than good, as the whales’ intent is unknown and may play an important role in natural selection. Sadly, all bleached whales that have been reverted back to their natural color have dyed.
