Do you know any WEIRD amazing fact about octopuses?

Question

As you may have noticed, I've been asking about octopuses this time...

I need to write a paragraph abt them: misconceptions, classes, & trivia...

It's school...

Answer 1

1.They also change color according to how they are feeling. When they are scared, they turn white. If they are mad, they will turn red.
2.An octopus will only stay in a "house" for about two days, and then it will set off to hunt for food. It will most likely never return to the home. From there, the octopus will make a new house.

*************************************
............MISCONCEPTION..........

2.An octopus has three hearts.
Two hearts are used to pump blood to each of the octopus' lungs and the third pumps blood throughout the body.
3.Octopi are highly intelligent.
They are believed to be the smartest of all invertebrates and show great skill at problem solving (instead of relying on instincts).
............MISCONCEPTION...........
4.Octopi have arms, not tentacles.
It is a common mistake to refer to an octopus' arms as 'tentacles'. Tentacles are longer than arms. Tentacles usually have suckers only at their tips

........For incorrect answer of
......they eat with their stomach
We crush our food in our hard bill then rasp off bits with the radula (like a fingernail file) located in our mouths.

Answer 2

Some octopuses use their ability to change color for more than camouflage. They often express their emotions using color. If they are relaxed, they are a dull grayish brown or orange-tinged. If they are angry, they turn red. If they are scared, they turn white.

Also, in laboratory experiments, octopuses have been able to open jars. They have even been known to get out of their aquariums or climb aboard ships to open buckets of crabs!

Octopuses have no "blind spot" in their vision, as we do, because their optic nerves are bundled up behind their photoreceptors, rather than in front of them as ours are.

And yes, the correct plural of octopus is in fact octopuses, rather than octopi. (It does seem like it should be octopi, but it's not.) At least that is what my textbook says.

Answer 3

Other than the fact that the plural of Octopus is OCTOPI....

Octopuses have a relatively short life span, and some species live for as little as six months. Larger species, such as the North Pacific Giant Octopus, may live for up to five years under suitable circumstances. However, reproduction is a cause of death: males can only live for a few months after mating, and females die shortly after their eggs hatch, for they neglect to eat during the (roughly) one month period spent taking care of their unhatched eggs.
