I know it sounds ridiculous but do snakes have tails??? or all of the part are only head and body?? oh yes, about the neck also..do they have necks? 😆
June 22, 2005 at 2:19 pm #25248b_d_41501Participant
In my opinion, I think they have tails. Most material that I read refers to them as having tails also.
June 22, 2005 at 5:58 pm #25278
Yes they have both of them. They can be differentiated along the spine…
June 23, 2005 at 7:51 am #25334
Can we determine the tail by measuring from the anus? So, at the back of the anus is the tail?
June 23, 2005 at 9:18 am #25347skilbanParticipant
hmm im not so sure, in my opinion i think they do have tails but im not sure where the tail starts perhaps from behind the anus

Yes snakes do have tails. One of the caracteristic of all chordatas is that they have tail with postanal position. Therefor tail begins right after the anus and in most snakes it`s quite short (compare to the body length). In the legless lizards the tail is much longer comparing to the body (one way of distinguishing them). The ventral side of the snake tail has two rows of plates but only one row on the body (at least in Europe).
For the necks, probably. But only on the sceletal level. The first vertebra is definitely different from the others and makes the neck. But are the 2nd, 3rd and few others diferentiated I don`t know. I know that in snakes all body vertebras carry ribs.

Good point Beetle
June 25, 2005 at 12:53 pm #25435
You mean like viper which have two plated rows and the tail that can make sound??
and for the neck, is it mesured from the skull till the atlas bone (the first vertebrae segment)?
Oh..another question..many scientists said that in the early time, snake had legs but because of those legs they couldn’t move fast so the degeneratd them..is it true??

Now I don`t know what you mean? 😕 😳 I meant something like this OIIIIIIIIIIIII::::> I hope this is not more confusing. 🙂
Rattles in the rattle snakes are made of the remainings of the old skin after the molting and does not have much to do with this.
I would say that atlas is the neck vertebra but do some others vertebras make neck with it I`m not sure.
Well yes. That is the current theory. The more slender body shape of snakes is more adept for fast moving through the grass than the leged body of a lizard. There are some groups of recent lizards in wich you can observe possible way of evolution (legs, big body => smaler legs, slender body => no legs, long and snakish body).

Also, I believe snakes have rudamentry legs, legs that have withered away thru evolution until only vestiges of them exist. The tail would be the part that is posterior to the “legs” as in other animals.
June 26, 2005 at 8:14 pm #25500
Not all snakes have rudimentary leggs, only some. The boa is an example if my memory serves me right
July 4, 2005 at 8:02 pm #26050InuyashaParticipant
right, but remember at the embroy stage everything has a tail
July 4, 2005 at 8:49 pm #26059
Yes… Humans included.. And you can not say that we have a tail 8)
July 5, 2005 at 12:49 pm #26083
there is….my bio book (indonesia version) said that our koxigea is analogised as ‘tail bone’… 😆
July 5, 2005 at 2:43 pm #26098JamesParticipant
The term ‘tail bone’ is widely used for the coccyx bone.
August 8, 2005 at 1:28 am #28119MahlonParticipant
Yes, in fact all snakes do have tails.
The easiest way to see this is to look in many of the primitive snakes, aka pythons and boas. Vestigial claws are present to the left and the right of the vent on many boas and pythons. If you take a look at an xray (tried to find one on the internet but no luck) of such an animal you would see the vestigial hind legs tucked in inside the snake, with only one of the claws coming out externally.
As for the defining point of the tail in all snakes, that would seem to me to be defined at a certain vertebrate posterior to the vent.
Sorry best I can do as of right now, not alot of snake info out there on the web.
August 8, 2005 at 12:05 pm #28133
Hmm, I guess it’s because there’re not many reptilians outta there…What’s interesting to me is their vestigial legs…I almost can’t believe it that snakes prefer moving with no leg rather than using their legs…. 😉
August 8, 2005 at 12:32 pm #28135iri_blackParticipant
More evolved snakes, although dont’t have vestigial legs, have protuberances at the spie level that show legs were present and innervated (brahial plexus and lumbar plexus).

snakes have tails(anus to tip of tail)
many south american constrictors have “spurs” especially the females, these are believed (by some) to have once been legs,which begs the question, whered the front 2 go?
as for necks…. fromthe base of the jaw muscle you have a pretty much square area (Width across @ smallest point behind head X length = to that width) that is considered the neck.
am i the only snake nut on this site?

Snakes have tails, but their bodies have such special shapes so it’s a lil bit difficult to recognize the tails. But they do.
August 29, 2005 at 7:27 pm #29005
Snake nut? Probably. Because
1. It is kind of a rare hobby
2. Each person is a nut about something else

That’s the funniest portrayel of a snakes tail i’ve ever seen…

In a recent trivia quiz was the question "Which animal in the Chinese zodiac does not have a tail?"
Answer: The Snake
And I would say they do not have a neck – as Fish do not have a neck –
Not all chordates have a tail – we are chordates – we do have a coccyx, but we do not call it a tail.

Hi Victor. A snake’s body is much the same as any other animal’s, except that they have no limbs ears or eyelids, and they have many more ribs than other animals. They certainly have tails.
August 27, 2013 at 10:28 am #114250elizabeth35Participant
Some snakes have tails that enable them to hold onto branches or vines to assist them in climbing trees. And of course a rattlesnake uses its tail as a warning device when it is scared. Many harmless snakes also vibrate their tails, and if they happen to be lying in dried leaves, they too make a rattling sound.
