wtf

Well it IS correct about the baby anteaters. Washington DC zoo, yewhaw!

Well, mine is red.

But I'm human, so...

The blood of horseshoe crabs is blue.

Really? That's cool!

You can drain up to 1/3rd of their blood out and they're totally fine as well.

The thing is that they have very low oxygen requirements, being cold blooded and having little actual flesh (they are mostly carapace). So they don't need much blood, and it doesn't have to be highly oxygenated.

Also, your blood is red because it uses Fe+3 (iron) ions to capture oxygen. Horseshoe crabs use Cu+2 ions (copper) to do the same.

So why would mammals, birds and other land animals all use iron-based blood? Partly it's a fluke of nature. All creatures with a spinal chord use hemoglobin (iron-based) blood because they are all descended from the same creature, while many non-spinal chord based creatures use hemocyanin (copper-based) instead. Mollusks, shellfish, arachnids, and many other inverebrates all have blue blood, it's just that they have so little blood that you don't notice it is blue when you crush them.

Additionally, hemocyanin is only 1/4th as efficient as hemoglobin. As such, it can only support creatures with a very low metabolism, which is one of the reasons why it's used by animals which do not move much (spiders, mollusks, etc. are not known for their migratory habits). Without hemoglobin it would not be possible for you to get the oxygen needed to support your higher level organs like your brain, eyes with dynamic lenses, an advanced internal digestive system, a pancreas which secrets billions of chemical messages, a liver which can filter out most poisons, etc.

SCIENCE.

That's really, really cool. You're just a fountain of information!

Well I had to look some of the specifics up on Wikipedia ;P

nope.. its actually blue

Mine looks green sometimes. My hands look really weird.

I've pretty much grown to accept that brains come up with weirdness.

It is if it's spread thin. :v

You need to apply Q-Tips to that thing... your brain's... odd.

"And it ain't sweet,
or some neat treat;
so please don't spread it on toast."

But it's best on toast, with a little garlic.

anteaters, you say?

BABY ones! I can't wait!

The stupid little poem is actually pretty awesome. :O

Aww, thank you!

The "stupid little poem" actually cements, for me, the creepy-coolness of this picture. Hell yes, Pie.

And do enjoy the baby anteaters.
