Marine biologists in England got their hands on a six-armed octopus, the discovery is significant since octopuses have 8 arms
Octopuses are highly sophisticated marine molluscs with 3 main defense mechanisms including ink injection, camouflage by changing color and the ability to regrow severed limbs. The organ growth mechanism allows the octopus to lose an arm and later grow another arm in its place. Indeed, some researchers claimed that "Henry" actually lost 2 of his arms and was left with only six arms.
But the staff and other marine researchers rejected this claim since a closer examination of the arms reveals that there is a membrane connecting all six arms so it is impossible for Henry to have lost any arm. When an octopus loses an arm, space is made for a new arm to grow in the future, and since there are no gaps between Henry's six arms, this is evidence that Henry was born with six arms. The prevailing hypothesis among researchers is that it is a birth defect.
The octopus was taken from the local zoo along with 7 other octopuses for a new exhibition held at Blackpools Marine Centre. No one noticed the missing arms until he was pressed against the clear glass.
The researchers tried to examine whether six-armed octopuses had been discovered in the past. After consultations with other maritime centers, experts in the field and a review of the professional literature and a scan of the Internet, they were amazed to discover that apart from science fiction films, a similar case had never been documented.
It should be noted that octopuses are very special invertebrates. They have no skeleton in their body and their head is directly attached to their arms. They have 3 hearts and blue blood flows through their bodies. They can change their body color at any given moment and thus disappear from the eyes of the predators. Studies and observations have taught that octopuses are very intelligent animals, they have short-term and long-term memory, they are creative and capable of self-learning.

"Find one and fry it" how hungry they are there, oh God
Another one like this was discovered today 28/7/2013 A man in Greece found one and fried it and then he found out that it is a very rare species! Look at Mako HIX.
(appears in the link)
Six arms to be exact!
In the last few hours, the following subtitle was added:
looked like it just held the shark still until it suffocated since there wasn't any wounds or blood. Sharks must constantly move water over their gills to breathe and it's crazy that the octopus knows that weakness and exploits it like that. It didn't even eat the shark or chew on it or anything.
According to this the octopus is really intelligent: saves energy to get food.
The octopus is one of the most mystical creatures in the history of mariners.
Want (more) proof?:

Bye
How many times can you write the "six" arms? In which grade do you learn to say six arms?
The above is also true for octopus as you can see here:http://en.wikipedia.org/wiki/Octopus
See for example here:
http://www.experiencefestival.com/a/Cuttlefish/id/2035057
Many things are written there, but among other things it also says:
The blood of a cuttlefish is green-blue, as they use the pigment hemocyanin to carry oxygen instead of the red hemoglobin that we use
What makes their blood look blue?
Regarding the above:
This, of course, also depends on the question of whether the mutation did not spoil the sexual compatibility between the goshawk and the octopuses, that is to say that when it is fertilized with a normal octopus, offspring will be produced.
It is probable, by the way, that the mutation is dominant because it is hard to believe that he received such a mutation from both of his parents (although it is possible because it is possible that such octopuses exist and we simply did not see it and it could even be probable in the case that it is a recessive mutation that when it appears in a double occurrence is also sterile). In such a case it is expected that half of the offspring will be witty
Gil Dotan and Assaf:
Who said it was a "disposable" mutation?
A mutation may be inherited and a mutation that determines the number of legs must be one that happened at an early stage so it is likely that it is completely innate and is also found in the gametes.
In this case, we may be witnessing the relinquishment of a new species. I also thought that in Hebrew it would be appropriate to call it Shashann and Blaze the Xapos.
It is interesting if it is possible for man to be able to isolate the gene that allows him to regrow organs and plant the same gene in humans.
This could have interesting consequences.
Can someone give a better explanation of their origin and whether it is only used for food
And is this something that renews???
I don't know what came over me if all this interest
I'm guessing it's a one-off mutation.
Both squids and octopuses have beaks.
They both have a common father, one of whom is still alive.
The VAMPIRE SQUID may be an earlier stage in development
http://en.wikipedia.org/wiki/Vampire_Squid
As far as I know some of the squids have a beak,
But not for octopuses.
It's a shame to get excited in vain, according to all the signs this is a flaw
If it wasn't a flaw, it wouldn't be an octopus but a clever one,
In the original news it is stated that according to all the indicators this is the case
"damaged" octopus,
Octopus doesn't have a bone??which is considered a bone???
I wonder what will happen if they put him in with a regular octopus.
