If an octopus loses two legs, does it become a sextopus?

No they are really smart these days. King Triton has learnt how to make artificial limbs for all the sea-creatures. I heard that Ariel, the little mermaid has just had breast implants

Many organisms possess vestigial structures that have no apparent function, but that resemble structures their presumed ancestors had. Humans, for example, possess a complete set of muscles for wiggling their ears, just as a coyote does (table 22.1). \n\nBoa constrictors have hip bones and rudimentary hind legs. Manatees (a type of aquatic mammal often referred to as "sea cows") have fingernails on their fins (which evolved from legs). Figure 22.17 illustrates the skeleton of a baleen whale, which contains pelvic bones, as other mammal skeletons do, even though such bones serve no known function in the whale. The human vermiform appendix is apparently vestigial; it represents the degenerate terminal part of the cecum, the blind pouch or sac in which the large intestine begins. In other mammals such as mice, the cecum is the largest part of the large intestine and functions in storageusually of bulk cellulose in herbivores. Although some suggestions have been made, it is difficult to assign any current function to the vermiform appendix. In many respects, it is a dangerous organ: quite often it becomes infected, leading to an inflammation called appendicitis; without surgical removal, the appendix may burst, allowing the contents of the gut to come in contact with the lining of the body cavity, a potentially fatal event.\n    \nThe skeleton of a baleen whale, a representative of the group of mammals that contains the largest living species, contains pelvic bones. These bones resemble those of other mammals, but are only weakly developed in the whale and have no apparent function.\n    \nIt is difficult to understand vestigial structures such as these as anything other than evolutionary relicts, holdovers from the evolutionary past. They argue strongly for the common ancestry of the members of the groups that share them, regardless of how different they have subsequently become. \nComparisons of the anatomy of different living animals often reveal evidence of shared ancestry. In some instances, the same organ has evolved to carry out different functions, in others, an organ loses its function altogether. Sometimes, different organs evolve in similar ways when exposed to the same selective pressures.

I will go with two actual legs

Yes..as weird it may sound. Their trunk acts like a 5th leg.\n \nJust like a spider monkey, where the tail acts as fifth arm.

Possibly something about their life span (they live only about a year or two) or the fact that an octopus is really just a giant squid.  Or that they are sometimes known as "devil fish".  Or that they are masters of disguise and use camouflage well.  These sites should give you lots of ideas.  I hope this helps.

Not the tailbone; probably not arm or leg bones- ribs are pretty important, so are the spine and the skull

Actually, it's a pretty good explanation.  It fits the observation.  Do elephants swim that well though?  Would one sink if it lost it's footing? <Looks it up>\n\nApparently, they do swim rather well in deep water.  So, it does seem to fit.  That would explain the lack of a head (based on apparent size of the neck) in the famous Nessie photo.

Answerer 1 and answerer 4 are both correct in the majority of squid species. However, in the giant squid, and some bodies have been found and dissected, the male contribution can be stored in the female body for a long period of time until she is in need of being fertilized. This is why giant squid are thought to be solitary animals unlike the majority of squid which have no ability nor any need to store anything because those are in large groups of squids constantly.

Looks like a cephalopod.

None - Cuttlefish have tentacles.\n\nCuttlefish are marine animals of the order Sepiida belonging to the Cephalopoda class (which also include squids, octopuses and nautilus). Although the name suggests it, cuttlefish are not fish, but molluscs.

Man, of course! In King Oedipus (Sophokles), the same question is asked by the Sphynx. You have 4 legs when you are a baby (you can't walk, it's the morning of your life), then you walk on 2 legs later on, and when you are old, your third leg is the stick you lean on.

>>>>how many legs of a centipede. \n\nI think you meant to ask "How many legs HAS a centipede?". Actually given your grasp of grammar you probably meant to ask "How many legs does a centipede have?".\n\n\nThe answer is that it varies, anywhere from eight to over a hundred depending on the species.\n\n>>>>>>>Are the number of legs for a crab is always constant?\n\nI think you meant to ask "Are the number of legs for a crab always constant" or "Is the number of legs for a crab always constant".\n\nThe answer is that, barring accidental amputation, all ADULT crabs have 10 legs. Many people believe they have 8 legs, but crabs also have a pair of swimming legs that they keep tucked against the body when they are on land.\n\nJuvenile crabs can have just 6 legs.

I suppose, but where would its tail go?

ants have six legs, so if they loose one or two they are still fine. And they don't feel the same kind of hurt than we do (at least they don't have pain receptors of a type which is comparable to ours), so an ant with a damaged or even missing leg may just walk on without being too much bothered by it. Watch their behavior, it will tell you how bad they feel (give it a minute or two).\n\nSo if you just damaged one of its legs, you should let it live, because it still can live on quite nicely. If you stepped on part of its body it is probably kinder to kill it completely because it is not going to be able to live on anyway.

octopus:  The big part is called the mantle.\nsnail:  The underneath is called the foot.

I think you mean hermaphrodite. That is an organism (even human, but rarely) that has both male and female sex organs.
