惊人的章鱼

While studying marine biology in college, one of my favorite stories was about a marine research lab that housed many tanks containing different animals in one room. With no explanation, crabs went missing from several tanks, all gone without a trace.

经过几次事件，研究人员安装了监视摄像头，以观看坦克过夜。低调地看，他们每天晚上看到一个章鱼从其坦克上爬出来，进入螃蟹坦克并吃掉它们，然后在早晨之前回到自己的坦克。我很确定，如果给了几天，章鱼would have figured out how to block the security camera too!

Smart with Sight and Touch

章鱼很棒。他们不仅具有超凡魅力 - 他们的移动方式和改变潜水员的色彩 - 他们也很聪明。1zplay研究人员经常研究大脑的大脑与某些鸟类和哺乳动物一样大。涉及迷宫和解决问题的实验表现出对长期和短期记忆的能力。

Like humans, octopus eyes have irises, pupils, lenses, and retinas, giving them advanced sight for an invertebrate. They also have an excellent sense of touch and their eight arms contain two thirds of their neurons. This means only part of their nervous system is in their brain and the rest is in their arms.

Divers love to watch octopi change color and flash different patterns on their skin. This occurs due to tens of thousands of色谱，覆盖章鱼。染色体是有色细胞，由于它们周围的肌肉收缩或缩回，可以改变颜色。似乎还不够，它们也有虹膜粒子或皮肤上的反射性细胞，可以反映周围环境的颜色，从而帮助它们与环境融为一体。

What Are They Called?

Another reason to love octopi… wait let me digress for a moment. Do we call them octopuses or octopi? Actually they’re both wrong, since the word octopus is a Greek word, the plural should be “octopodes” – but no one uses that. ‘Octopuses’ is generally argued to be correct, as the –es suffix is proper English. Octopi uses an inappropriate Latin suffix (-i) on a Greek word that has been used in English for a long time. Anyway, both forms are commonly used, so I’m going to use them both here just to mix it up a little- but ‘octopuses’ is correct.

On Love

So back to the octopodes’ love – how could you not love something with three hearts? Yes- that’s right- octopuses have three hearts. And if that’s not enough to love, just remember they have eight arms to hold you with.

继续以这个主题为主题，从一个可爱但经常短暂的求爱开始，雄性章鱼从中转移一包精子hoctocotylus(one specialized tentacle) into the females mantle – think of it as the male caressing her slightly on the back of the neck.

可悲的是男性被认为死后不久,this exchange, whereas the females find a den to lay their eggs and protect them till they hatch, without leaving even for food. Females die shortly after their new generation is born. Some female species carry their eggs on them until they hatch.

Other Cool Stuff

One more cool fact: octopuses have blue blood. This comes from a copper-containing protein called血红蛋白结合氧；同时，人类的血红蛋白含有铁使其发红。

When they’re angry – watch out – octopuses can “ink” predators (or annoying divers). The black cloud of ink is meant to distract or confuse predators, giving the octopuses a chance to escape.

从最微小的毛茸茸章鱼，只有几英寸宽，到太平洋巨大的章鱼，臂跨度超过15英尺，章鱼有各种尺寸和颜色。直到最近才发现，Wonderpus和Mimic Octopuses的五颜六色的身体使摄影师感到高兴，更不用说模仿章鱼弯曲其身体的方式，假装是其他动物，例如Flounder Fish鱼，海蛇，lion鱼等。

微小的蓝色戒指章鱼具有美丽的蓝色和红色飞镖图案，是致命的。它产生含有许多神经毒素的毒液，其中一种毒素至少比氰化物高10,000倍。所有这些都来自一个可爱的章鱼，可以放在您的手掌中 - 但永远不要把它放在手中！

我们还可以通过使用工具来判断情报 - 我可以介绍椰子章鱼吗？这个太平洋物种使用椰子壳进行保护和家。如果要搬家，椰子章鱼只会捡起并将其携带。

So as you can see, the octopus is amazing. I hope you see one on your next dive!
