Red-green color blindness affects up to 8% of men but only 0.5% of women.

282

Humans have 3 types of "cone" cells in their eyes which detect different wavelengths of visible light. But birds have four. This allows them to see ultraviolet light that humans cannot. Some birds have brilliant markings that are only visible in the ultraviolet spectrum.

283

Mantis shrimp have a "punch" that is so powerful it can break aquarium glass.

284

There was once a chicken that lived for 18 months without a head. His name was Mike.

285

Greenland sharks are thought to be the longest-lived of any vertebrate species with an estimated life span of 300-500 years.

281 makes sense, I'm pretty sure that women can see more shades of red than men

That's not it dude. it's the fact that it's on the X chromosome so men can't be carriers- they either have it they don't. Women need a mom that's carrier and a dad who's colorblind.

In men, cranberry, scarlet, cardinal, maroon, imperial red, Spanish red, carmine, crimson, etc are just 'red.' Women tell you to get the imperial red whatever and get mad when you pick the crimson red whatever.

I see red when when they get alizarin, quinacradone red, rose madder, cadmium red, when all I really wanted was permanent rose.

there is a rare genetic disorder in humans that gives them 4 cones, up to 50% of women and 8% of men have it: this probably explains why women can differentiate imperial red, crimson, carmine, etc.

In addition to mantis shrimp's powerful punch, they also have the most advanced sense of sight ever discovered - far beyond that of humans!

That's true, you never see a shrimp with spectacles.

It's not exactly having a fourth cone that allows birds to see light in the ultraviolet spectrum. The additional cone would allow them to distinguish between colors that look identical to us, but being able to see light in the UV spectrum is related to what range of frequencies of light each type of cone is sensitive to. For example, most mammals, including reindeer, only have two types of cones, but reindeer are the only mammals to be able to see UV light. This is because one of their two cones is sensitive to a range of light that includes light in the UV spectrum.

I believe the punch of the mantis shrimp's dactyl heel was thought to be the fastest reflex in the animal kingdom, but it is now thought to be narrowly superceded by the snapping mandibles of the trap-jaw ant. It's bite is so intense that if it bites the floor, it can go flying through the air.

#285 is probably true. However, that's 300 years of utter boredom, swimming around in cold, dark waters, waiting to be blinded by eye-parasites. Boring.

Mayflies? Complete opposite: at most, two days of full-tilt, pedal-to-the-metal, voracious living...then death.

If I recall correctly, most animals don't really perceive boredom—all they know is survival.
