'HEART' to believe!!!! 難以置信!!!!

You may be freaked out when you hear this; an octopus has THREE hearts!!!!

Really (no kidding). That’s the mystery of nature. You keep wondering why God gives an octopus three hearts. You’d think that octopuses are loving and kind because they have a BIG heart!

Don’t get me wrong. I wouldn’t try to hug an octopus in case it tries to strangle me with its slimy and slick tentacles. And probably ooze some ink at me for disturbing it.

So WHY do octopuses have that many hearts? Two smaller hearts are actually used to pump blood to the gills. The blood loads up on oxygen here, and then goes to the main heart. This oxygen-rich blood will then be pumped out through the octopus’ body.

And guess what? The blood is not red, like us human’s. An octopus’ blood colour is ACTUALLY blue!!!! That’s because octopuses have a protein called hemocyanin, which causes their blood to be BLUE! Ours is RED because we have a protein called hemoglobin.

THREE hearts? BLUE blood? (They could be royal descendents. Who knows?)

That’s ‘HEART’ to believe.



如果我告诉你章鱼有三颗心脏,你可能会吓了一跳!!!!

真的(我没骗你)。这就是大自然的神秘之处。你可能觉得奇怪为何上帝给了章鱼三颗心脏。你可能以為章鱼是具有爱心又善良的,因为他们有颗很大的心!

千万別误解我的意思。我沒有想拥抱章鱼,免得它用粘液和光滑的触角扼住我,使我动弹不得。也许还会朝我喷墨水呢!

那为什么章鱼有许多颗心?两颗较小的心脏可以将血液输送至鳃。血液装载了氧气后,就输送至主要的心脏。充满氧气的血液将会通过章鱼的身体被输送到体外。

你猜到了嗎?章魚的血液不像人类是红色的,而是蓝色的!这是因为章鱼的体內有一种蛋白质称为血蓝蛋白,导致他们的血液是蓝色的!而我们的血液却是红色的,这是因为我们的体內有一种蛋白质称为血红素。

三颗心脏?蓝色的血液?(他们有可能是王室的后裔哦!谁知道呢?)

真是難以置信。
