Talk:Snake/Archive 3

Hey guys, I would like to add information and my own dissected picture of a snake's heart under the Internal organs section. This is important because snake's have a three-chambered heart that is different than the mammal's four-chambered heart in delivering blood and oxygen since snake's have an elongated body. Tell me what you guys think. A couple of articles that I have found regarding the heart are:

• "Circulation in the Three-Chambered Snake Heart" ^[1]
• "The heart of the South American rattlesnake, Crotalus durissus" ^[2]

Here is what I think should be added: Though most people think all snakes are deadly and venomous,only about 500 snake species out of more than 3,000 are venomous, and of those only 30 - 40 are considered harmful to humans. Statistically speaking, less than 2 percent of all snakes are considered harmful to humans. Varunpopo (talk) 00:59, 20 February 2020 (UTC)

Snakes might have evolved during the Jurassic period. There is a 2018 report called "A Preliminary Report of the Fossil Mammals From a New Microvertebrate Locality in the Upper Jurassic Morrison Formation, Grand County, Utah", this paper describes snake fossils from the Morrison Formation (which dates tot he Jurassic). Would we want to include this in the time line as a possibility or wait or more conclusions. This paper is newer than the one we use for the snake timeline. --Bubblesorg (talk) 15:54, 28 May 2020 (UTC)

The current age is for the crown group, i.e. the common ancestor of all living snakes and all its descendants. The Parviraptor or Diablophis. is well known in recent years as a lineage of early snakes but they probably do not belong to the crown group. Lythronaxargestes (talk | contribs) 07:16, 30 May 2020 (UTC)

The paper is showing Serpentes indent, Serpentes is the crown group. This is not showing Parviraptor or Diablophis. But sure, I would agree to keep it out for now--Bubblesorg (talk) 19:53, 3 June 2020 (UTC)

The discussion of snake digestion within the "Feeding and Diet" section could be expanded to include more information about the adaptations snakes have for digestion at lower temperatures. More information could also be added to explain in more detail how the digestive system works to break down the animals that had been eaten whole beyond just mentioning that there's an enzyme, and if all snakes or certain groups of snakes have distinctive digestive processes, organs, or enzymes.

@Peteruetz: Hi Peter, I just wanted to check out your sourcing for the number of species. I understand that my WorldAtlas source might be a little out of date, but I think it's a more suitable source for the number of species because it makes the definitive statement: "There are approximately 3,600 known species of snakes in the world." The page isn't particularly out of date as it was published in January 2019 (according to the page source code). I'd suggest using this with a conclusive dated statement like: "As of January 2019, there were approximately 3,600 species of snakes."

I'm concerned that the main page of your website does not state anywhere that there are about 3,900 species (unless I'm not looking in the right place) which is the info that needs to be verified. This is also why I'm concerned about a WP:COI issue because you clearly know your own website inside out, but the casual reader would not know how to navigate to find the relevant information. If we were to use your site, might it not be better to give the search results link used elsewhere in the article (ref.5)? It at least provides an up-to-date number that is clearly visible to the reader (today it says 3879) but that link may be overused in the article already, which suggests that an alternative source should be used elsewhere. Regards, Rodney Baggins (talk) 10:28, 8 March 2021 (UTC)

Hi Rodney, I agree, the link to the search result is the better solution rather than the home page.

However, there are other ways to find that number, e.g. a link on our main web page saying "How many species?", which also yield 3,879 snake species (in Dec 2020) and you can actually use the quick search on the same page which gives you 4006 species (which is not exactly correct as that will return all entries that mention the word "snake"). However, you are also right that the Advanced search is only one click away from the main page and you can search the higher taxa for snake, which again will give you 3,879 snake species, and that list is not only up-to-date (except for species described since December), but also provides all the gory details on every single one of them (once you click the links).

https://www.thesun.co.uk/news/12541253/snake-pulled-throat-slither-sleep-video/ - this case was covered by several different news sources and includes a video. In the footage you can see a four foot long snake is being removed from the woman's stomach. In the area the woman hailed from, it's said that it's an occasional occurrence, and people are warned not to sleep outdoors for a snake could crawl into a person's stomach through their mouth and make a home there. Perhaps this behaviour should be added to this article? — Preceding unsigned comment added by 109.180.79.70 (talk) 19:29, 28 November 2021 (UTC)

One way is to check for expandable jaw, because snakes have them, while lizards don't and can only eat prey smaller than it's mouth. However, is this clear in fossils? Not sure if jaw bones become fossilized, or if there is enough detail to make out a difference. How do paleontologists know they are looking at evolution of snakes, and not evolution of legless lizards?--111.201.79.153 (talk) 19:57, 23 November 2018 (UTC)

Their body plans are very different. Legless lizards are just lizards only without legs. On the other hand snakes have significant axial skeleton modifications: much shorter tails, increased number of thoracic vertebra and reduced number of neck, lumbar and pelvic vertebra. There are likely other less significant differences. Ruslik_Zero 18:59, 24 November 2018 (UTC)

Hello all,

I am looking at adding info about the relationship between ecdysis in snakes and reproduction, specifically adding the line “It’s also been observed in snakes that molting can be synced to mating cycles. Shedding skin can release pheromones and revitalize color and patterns of the skin to increase attraction of mates” to the molting section of this article, right at the beginning of the section as this is another purpose of molting in snakes.

Here are my main sources: Synchronization of Spring Molting with the Onset of Mating Behavior in Male Lizards, Lacerta vivipara and Synchrony of Ecdysis in Snakes

Wanted to see if anyone had any thoughts on this addition as I know this is a big article.

There is plagiarism in the second paragraph in the molting section from this archived source: https://web.archive.org/web/20060805131135/http://www.szgdocent.org/resource/rr/c-slimy.htm

There was also plagiarism in the first paragraph from this book that I tried to change.

Also section could benefit from different wording in several areas

It might be helpful to add the sentence that from a cladistic point of view, snakes are lizards (several lizard species are more closely related to snakes than to at least one other lizard species), just how the article for birds states that birds are cladistically reptiles. Since cladistics teaches that no organism can evolve out of a clade, this makes snakes a subgroup of lizards. 2409:4042:4D9B:4484:0:0:380B:7100 (talk) 12:27, 19 March 2024 (UTC)

Most of the first paragraph in the "Molting" section would fit better in the parent "Skin" section, as it describes how the scales work and not reasons for/the mechanics of molting. I suggest that it should be in between the second and third paragraph of the "Skin" section. The second sentence also needs some help, and I suggest this change:

"For a snake, the skin has been modified to its specialized form of locomotion"

The first and last two sentences should be kept in the "Molting" section, and the beginning of the "Molting" section would now read like this:

"Molting (or "ecdysis") allows for old, worn skin to be replaced by newer skin with revitalized colors and patterns. Molting occurs periodically throughout the life of a snake. Before each molt, the snake regulates it's diet and seeks defensible shelter. Just before shedding, the skin becomes grey and the snake's eyes turn silvery. The inner surface of the old skin liquefies, causing it to separate from the new skin beneath it. After a few days, the eyes clear and the snake reaches out of its old skin, which splits. The snake rubs its body against rough surfaces to aid in the shedding of its old skin. In many cases, the castaway skin peels backward over the body from head to tail in one piece, like taking the dust jacket off a book, revealing a new, larger, brighter layer of skin which has formed underneath.[58][62] Renewal of the skin by molting supposedly increases the mass of some animals such as insects, but in the case of snakes this has been disputed.[58][60] The process also releases pheromones that increases the attraction of mates.[61]"

I hope this suggestion helps make the section more understandable. BitUniverse (talk) 20:09, 1 May 2024 (UTC)

Garter snakes were long thought to be non-venomous, but discoveries in the early 2000s revealed that they produce a neurotoxic venom. Despite this, garter snakes cannot seriously injure or kill humans with the small amounts of comparatively mild venom they produce and they also lack an effective means of delivering it. Common garter snakes can grow to a length of 86 cm (34 in), though they are commonly shorter. Females are larger than males and have longer tails. They are typically black, brown, gray, or green, and many have irregular red spots. Three brightly coloured (usually yellow but sometimes white, green, or brown) stripes—matching the coulour of their underside—run along the length of their bodies, though sometimes the stripes are missing or are not well defined. Regional coloration varies, and in southern Oregon and northern California, a common subspecies, the valley garter snake (Thamnophis sirtalis fitchi), has a bright yellow dorsal stripe and bright red spots along the body. Garter snake heads are wider than their necks, and their tongues are red, tipped in black. The scales of the common garter snake are keeled, meaning they have a raised ridge along their length. Common garter snakes inhabit most of North America. While common garter snakes are highly adaptable and capable of surviving in extreme environmental conditions, they prefer to live in moist grassy environments and are often found near permanent surface water, like ponds, lakes, and streams, in part because they can flee into water when threatened. They use dens under rocks and other structures. As long as they have a suitable place to hide from predators, they can live in both urban and suburban areas. They are active during the day, using their sense of smell and good vision to hunt. Common garter snakes consume a variety of prey, including earthworms, amphibians, leeches, slugs, snails, insects, crayfish, small fish, and other snakes. To help them control prey while eating them whole, common garter snakes produce toxic saliva. Common garter snakes typically brumate (the reptile version of hibernation in mammals) from late October through early April in natural cavities or burrows. While common garter snakes are usually solitary, they congregate in large numbers, including with snakes of different species, during the winter. One unique trait of the common garter snake is that it coevolved with the rough-skinned newt (Taricha granulosa), each animal driving the other to adapt. Rough-skinned newts have glands in their skin that produce a powerful neurotoxin that is lethal to most predators. Common garter snakes have evolved resistance to the toxin. In turn, rough-skinned newt populations that are preyed on by garter snakes respond by producing more potent toxin. In this way the two species have become locked into what is referred to as an evolutionary arms race. Common garter snakes have been documented in Crater Lake National Park, Redwood National and State Parks, Lassen Volcanic National Park, and Lava Beds National Monument, but are likely present in all Klamath Network parks. — Preceding unsigned comment added by Coolswaks2212 (talk • contribs) 18:18, 13 August 2025 (UTC)
