2. They are so intelligent

and escape artists too - able to get through the tiniest holes. I love this. Thanks for sharing!

5. Octopuses have beaks

If the opening is big enough for the octopus’s beak, it’s big enough for the whole octopus.

3. Such amazing creatures

That's a really little one.

4. The octopus is absolutely fascinating to behold and a marvel of nature.

And it is almost eerie how their eyes are so similar looking to ours...
