What is Reddit's opinion of Peterson Field Guide To Reptiles And Amphibians Eastern & Central North America (Peterson Field Guides)?

When I took Herpetology in college, we all had to buy a Peterson's Guide for lab. That's where I started. Next, I check this sub multiple times a day and try to ID the snakes.

Snake head shape is also a bad idea. Most snakes will flatten their head when threatened or preparing to strike. Think of what cobras can do, but not so extreme. This is to puff up and look more threatening. This isn't 100% universal, but a common behavior.

Yes your rattle snakes of the family Crotalidae/Viperidae do have very prominent head shape, but the rattling is such a better way to pick them out. Contrasting, the coral snake, Micrurus tener, has a very round head, looks very similar to milk snakes, however their neurotoxin venom will kill you.

EDIT: Best advice I have is to just pick a field guide of your region and read it. (https://www.amazon.com/Peterson-Reptiles-Amphibians-Eastern-Central/dp/0544129970) Other then that, just let the sneks be sneks and slither away!

I'll just copy and paste what I responded to earlier in the comment thread. Too lazy to type.

There are a number of resources for snake ID and this list is nowhere near comprehensive.

Globally, comprehensive species lists are available via Reptile Database Advanced Search. Reptile Database is mostly correct and up to date in terms of taxonomy. Another worldwide resource is Snakes of the World which, in addition to being comprehensive for extant snakes, also provides a wealth of information on fossil taxa.

Regional guides are useful. If you're in North America, the Eastern Peterson Guide and Western Peterson Guide are great tools, as is Snakes of the United States and Canada. While plagiarized and problematic, the book Snakes of Mexico is the best easily accessible information for the region. For Central America, the Kohler book as well as Savage's Costa Rica book are excellent resources. South America is tough but has a diagnostic catalog. Australia has Cogger as a herp bible. SE Asia has two guides one in German and one comprehensive. For Europe, you simply can't get better than the three volumes of Handbuch der Reptilien und Amphibien Europas. Africa is also difficult - no comprehensive guide exists but there are a few good regional guides like Reptiles of East Africa and Guide to the Reptiles of Southern Africa. Amphibians and Reptiles of Madagascar is a good source for that distinct region. For the Indian subcontinent, use Snakes of India

Remember, species names are hypotheses that are tested and revised - old books become dated by the nature of science itself. One of your best resources is going to be following /r/whatsthissnake, or (for North America) with the SSAR Standard Names List for the most recent accepted taxonomic changes.

Brownsnakes Storeria dekayi are small (20.0-40.0cm record 52.77cm) natricine snakes often found in disturbed habitats like urban and suburban yards. They are one of the most commonly encountered snakes in eastern North America and make good pest control as they feast on small, soft-bodied invertebrates.

A separate but distinct species, Storeria victa occupies peninsular Florida. It has two fewer midbody scales (15) than Storeria dekayi and is more likely to have yellow collar markings on the neck.

Storeria brown and redbelly snakes are not considered medically significant to humans in terms of venom and are usually reluctant to bite, but all animals with a mouth can use it in self-defense.

Everyone loves cats, but they belong indoors. Each year in the United States free-ranging domestic cats kill 1.3-4.0 billion birds and 6.3-22.3 billion mammals. Numbers for reptiles are similar in Australia, as 2 million reptiles are killed <strong>each day</strong> by cats, totaling 650 million a year. Outdoor cats are directly responsible for the extinction of at least 33 species worldwide and are considered one of the biggest threats to native wildlife.

Please leave wild snakes in the wild. This includes not purchasing common species collected from the wild and sold cheaply in pet stores, like Thamnophis Ribbonsnakes and Opheodrys Greensnakes. Snakes are kept as pets or specimens by many people but captive bred animals have much better chances of survival, as they are free from parasite loads, didn't endure the stress of collection and shipment, and tend to be species that do better in captivity. Taking an animal out of the wild is not ecologically different than killing it, and most states protect non-game native species - meaning collecting it probably broke the law.

If you insist on keeping a wild pet, it is your duty to plan and provide the correct veterinary care, which often is two rounds of a pair of the 'deworming' medications Panacur and Flagyl and injections of supportive antibiotics. This will cost more than enough to offset that cheap price tag on the wild caught animal at the pet store or reptile show and increases chances of survival past about 8 months, but does not offset removing the animal from the wild.

Head shape is not a reliable indicator of if a snake has medically significant venom. Nonvenomous snakes commonly flatten their heads in defensive displays, and venomous elapids like coralsnakes have elongated heads. It's far more advantageous to familiarize yourself with venomous snakes in your area through photos and field guides or by following subreddits like /r/whatsthissnake than it is to try to apply any generic trick.

Like many other animals, snakes have mouths and can use them to bite in self defense. These animals are referred to as 'not medically significant' or traditionally, 'harmless'. Bites from these snakes benefit from being washed and kept clean like any other skin damage, but aren't often cause for anything other than basic first aid treatment. Some snakes use venom from front or rear fangs as part of prey capture and defense. This venom is not always produced or administered by the snake in ways dangerous to human health, so many species are venomous in that they produce venom, but considered harmless to humans in most cases because the venom is of low potency, and/or otherwise administered through grooved rear teeth or simply oozed from ducts at the rear of the mouth. Species like Ringneck Snakes Diadophis are a good example of mildly venomous rear fanged dipsadine snakes that are traditionally considered harmless or not medically significant. Similarly, but without specialized rear fangs, gartersnakes Thamnophis ooze low pressure venom from the rear of their mouth that helps in prey handling, and are also considered harmless. Even large species such as Malayopython reticulatus rarely obtain a size large enough to endanger humans so are usually categorized as harmless.

Pine Woods Snakes Rhadinaea flavilata are small (25-33 cm record 40.3 cm) nocturnal dipsadine colubrid snakes with smooth scales, part of a group of 20+ "littersnakes" found in the Western Hemishphere from North Carolina to Argentina. Pine Woods Snakes are found in pine flatwoods, sandhills and other damp areas with deep leaf litter. While they exist primarily on the Atlantic Coastal Plain, isolated populations are occasionally discovered. These snakes eat small ampbians, lizards, snakes and small mammals. As dipsadines, they kill by simply overpowering prey, moving larger items to the rear of the mouth where an oozey, low pressure venom is administered via specialized rear teeth. Range, a dark stripe through the eye and general two-tone color pattern can be used to distinguish this from other similar small snakes.

Keels are raised lines on the surface of scales that can be used as a character in snake identification to quickly narrow down options or distinguish between some similar looking species. Strength of keel is variable; usually referred to as 'strong' vs 'weak'.

Amphibians and Reptiles of Madagascar is a good source for that distinct region. For the Indian subcontinent, use Snakes of India

Remember, species names are hypotheses that are tested and revised - old books become dated by the nature of science itself. One of your best resources is going to be following /r/whatsthissnake, or (for North America) with the SSAR Standard Names List for the most recent accepted taxonomic changes.

There are a number of resources for snake ID and this list is nowhere near comprehensive.

Globally, comprehensive species lists are available via Reptile Database Advanced Search. Reptile Database is mostly correct and up to date in terms of taxonomy. Another worldwide resource is Snakes of the World which, in addition to being comprehensive for extant snakes, also provides a wealth of information on fossil taxa.

Regional guides are useful. If you're in North America, the Eastern Peterson Guide and Western Peterson Guide are great tools, as is Snakes of the United States and Canada. While plagiarized and problematic, the book Snakes of Mexico is the best easily accessible information for the region. For Central America, the Kohler book as well as Savage's Costa Rica book are excellent resources. South America is tough but has a diagnostic catalog. Australia has Cogger as a herp bible.

Here is an example of a small personal herpetology library.

Naming in biology follows a set of conventional rules. A species name has two parts. The first word, always capitalized, is the 'genus'. Take for example the Bushmaster, Lachesis muta. 'Lachesis' is the genus, a group of at least four charismatic, venomous, egg-laying pit vipers native to Central and South America. The second part, in our case 'muta', is the 'specific epithet', and is never capitalized. This particular specific epithet is 'muta' as in muteness, a reference to the this pit viper's rattle-less tail. With its granular, raised scales, the Bushmaster is reminiscent of a mute rattlesnake. The two words together form the species name, Lachesis muta. This name is also a species hypothesis about who is related to who - taxonomy reflects the evolutionary history of the group.

There are some good field guides that cover your area, and these are better and more efficient to help you learn your local species. You should pick up this one; you can find one used in good condition on eBay or Amazon for $12-

Peterson Field Guide to Reptiles and Amphibians of Eastern and Central North America, 4th Edition

You could also try the older, 3rd Edition Expanded, which is going for $9 used on Amazon. It's behind the times in terms of taxonomy, but it has more pictures, and it also includes more information about many species lifestyles and habits, which might be useful to a young student of the game such as yourself.

Globally, comprehensive species lists are available via Reptile Database Advanced Search. Reptile Database is mostly correct and up to date in terms of taxonomy. Another worldwide resource is Snakes of the World which, in addition to being comprehensive for extant snakes, also provides a wealth of information on fossil taxa.

Regional guides are useful. If you're in North America, the Eastern Peterson Guide and Western Peterson Guide are great tools, as is Snakes of the United States and Canada. While plagiarized and problematic, the book Snakes of Mexico is the best easily accessible information for the region. For Central America, the Kohler book as well as Savage's Costa Rica book are excellent resources. South America is tough but has a diagnostic catalog. Australia has Cogger as a herp bible. SE Asia has two guides one in German and one comprehensive. For Europe, you simply can't get better than the three volumes of Handbuch der Reptilien und Amphibien Europas. Africa is also difficult - no comprehensive guide exists but there are a few good regional guides like Reptiles of East Africa and Guide to the Reptiles of Southern Africa. Amphibians and Reptiles of Madagascar is a good source for that distinct region. For the Indian subcontinent, use Snakes of India

Remember, species names are hypotheses that are tested and revised - old books become dated by the nature of science itself. One of your best resources is going to be following /r/whatsthissnake, or (for North America) with the SSAR Standard Names List for the most recent accepted taxonomic changes.

Eastern Hog-nosed Snakes Heterodon platirhinos are harmless medium-sized (record 115.6 cm) dipsadine snakes with keeled scales native to the eastern North America. A similar species, Heterodon simus is native to the extreme southeastern US. It can be distinguished from Eastern Hog-nosed snake H. platirhinos by a more upturned snout and consistent belly coloration. Adults are relatively small, yet stocky, rarely exceeding 20 inches in length (44-55 cm, record 61 cm). The primary habitats for these snakes are dry uplands - particularly sandhill and scrub biomes - but they may occasionally be found in hammocks or transient wetlands. Like other hog-nosed species, an upturned snout is the defining feature of this snake used to burrow in the sand to search for toads and other small reptiles, which are their primary food source.

Eastern Hog-nosed snakes are highly variable in color, ranging from tan, brown, and olive to yellow and orange. Some individuals are entirely black. Hog-nosed snakes are known for their impressive threat displays, which can include loud hissing, puffing of the body, mock striking and flattening of the neck, however they rarely actually bite. This incredible act leads to being mistakenly identified as cobras or other dangerous species by people unfamiliar with this behavior. When excessively harassed, hog-nosed snakes are capable of "playing dead", which consists of them rolling onto their backs and hanging their mouths open, throwing their tongue out and spreading a thick musk secreted from the cloaca.

Although medically insignificant to humans, hog-nosed snakes deliver a mild, low pressure venom through grooved rear fangs. Common in dipsadine snakes, it helps to immobilize prey and reduce handling time. For more information, see this writeup by /u/RayinLA.

Like many other animals with mouths and teeth, non-venomous snakes can use them to bite in self defense. These animals are referred to as 'not medically significant' or traditionally, 'harmless'. Bites from these snakes benefit from being washed and kept clean like any other skin damage, but aren't often cause for anything other than basic first aid treatment. Some snakes use venom from front or rear fangs as part of prey capture and defense. This venom is not always produced or administered by the snake in ways dangerous to human health, so many species are venomous in that they produce venom, but considered harmless to humans in most cases because the venom is of low potency, and/or otherwise administered through grooved rear teeth or simply oozed from ducts at the rear of the mouth. Species like Ringneck Snakes Diadophis are a good example of mildly venomous rear fanged dipsadine snakes that are traditionally considered harmless or not medically significant. Many rear-fanged snake species are harmless as long as they do not have a chance to secrete a medically significant amount of venom into a bite; severe envenomation can occur if some species are allowed to chew on a human for as little as 30-60 seconds. It is best not to fear snakes, but use common sense and do not let any animals chew on exposed parts of your body. Similarly, but without specialized rear fangs, gartersnakes Thamnophis ooze low pressure venom from the rear of their mouth that helps in prey handling, and are also considered harmless. Even large species such as Malayopython reticulatus rarely obtain a size large enough to endanger humans so are usually categorized as harmless.

Here is an example of a small personal herpetology library.

Naming in biology follows a set of conventional rules. A species name has two parts. The first word, always capitalized, is the 'genus'. Take for example the Bushmaster, Lachesis muta. 'Lachesis' is the genus, a group of at least four charismatic, venomous, egg-laying pit vipers native to Central and South America. The second part, in our case 'muta', is the 'specific epithet', and is never capitalized. This particular specific epithet is 'muta' as in muteness, a reference to the this pit viper's rattle-less tail. With its granular, raised scales, the Bushmaster is reminiscent of a mute rattlesnake. The two words together form the species name, Lachesis muta. This name is also a species hypothesis about who is related to who - taxonomy reflects the evolutionary history of the group.

Globally, comprehensive species lists are available via Reptile Database Advanced Search. Reptile Database is mostly correct and up to date in terms of taxonomy. Another worldwide resource is Snakes of the World which, in addition to being comprehensive for extant snakes, also provides a wealth of information on fossil taxa.

Regional guides are useful. If you're in North America, the Eastern Peterson Guide and Western Peterson Guide are great tools, as is Snakes of the United States and Canada. While plagiarized and problematic, the book Snakes of Mexico is the best easily accessible information for the region. For Central America, the Kohler book as well as Savage's Costa Rica book are excellent resources. South America is tough but has a diagnostic catalog. Australia has Cogger as a herp bible. SE Asia has two guides one in German and one comprehensive. For Europe, you simply can't get better than the three volumes of Handbuch der Reptilien und Amphibien Europas. Africa is also difficult - no comprehensive guide exists but there are a few good regional guides like Reptiles of East Africa and Guide to the Reptiles of Southern Africa. Amphibians and Reptiles of Madagascar is a good source for that distinct region. For the Indian subcontinent, use Snakes of India

Remember, species names are hypotheses that are tested and revised - old books become dated by the nature of science itself. One of your best resources is going to be following /r/whatsthissnake, or (for North America) with the SSAR Standard Names List for the most recent accepted taxonomic changes.

Brownsnakes Storeria dekayi are small (20.0-40.0cm record 52.77cm) natricine snakes often found in disturbed habitats like urban and suburban yards. They are one of the most commonly encountered snakes in eastern North America and make good pest control as they feast on small, soft-bodied invertebrates.

A separate but distinct species, Storeria victa occupies peninsular Florida. It has two fewer midbody scales (15) than Storeria dekayi and is more likely to have yellow collar markings on the neck.

Storeria brown and redbelly snakes are not considered medically significant to humans in terms of venom and are usually reluctant to bite, but all animals with a mouth can use it in self-defense.

Naming in biology follows a set of conventional rules. A species name has two parts. The first word, always capitalized, is the 'genus'. Take for example the Bushmaster, Lachesis muta. 'Lachesis' is the genus, a group of at least four charismatic, venomous, egg-laying pit vipers native to Central and South America. The second part, in our case 'muta', is the 'specific epithet', and is never capitalized. This particular specific epithet is 'muta' as in muteness, a reference to the this pit viper's rattle-less tail. With its granular, raised scales, the Bushmaster is reminiscent of a mute rattlesnake. The two words together form the species name, Lachesis muta. This name is also a species hypothesis about who is related to who - taxonomy reflects the evolutionary history of the group.

North American Racers Coluber constrictor are large (record 191.1 cm TBL) diurnal colubrid snakes. They are generalists often found in disturbed habitats like urban and suburban yards but also do well in many natural habitat types. They are one of the most commonly encountered snakes in North America and have a huge range spanning most of the continent. They eat anything they can overpower, including other snakes of the same species, but are not obligate constrictors as the specific epithet might suggest.

Racers have smooth scales and color pattern varies clinally across their range, from steel gray to jet black, a blue "buttermilk" pattern you have to see to believe, to blue, green and yellow. These color patterns are tied closely to local environment and don't track evolutionary history. Baby racers start out with a blotchy pattern and darken over the first two years, losing it entirely. Racers are not considered medically significant to humans - they are not venomous, but all animals with a mouth can use it in self-defense. Racers are particularly, alert, agile snakes, and will sometimes stand their ground when cornered and/or bite when handled.

Often confused with keeled "black" ratsnakes (northern ranges of Pantherophis obsoletus, P. spiloides and P. alleghaniensis), racers Coluber constrictor have smooth scales. Indigo snakes Drymarchon couperi have orange on the face or neck and an undivided anal plate. In some cases they are difficult to differentiate from coachwhip snakes Masticophis flagellum, but on average have two more posterior scale rows (15) than M. flagellum.

Racers in peninsular Florida are phylogenetically distinct from those in the continent - the only deep population structure identified in racers. No formal elevation to species status has occurred yet, but it's not premature to say that genomic level data suggest racers found in Florida deserve full species status.

This short account was prepared by /u/Phylogenizer.

Eastern Ratsnakes Pantherophis alleghaniensis are large (record 256.5 cm) common harmless ratsnakes with a multitude of regional color patterns native to eastern North America. Pantherophis ratsnakes are keeled-scaled generalists that eat a variety of prey. They do well in urban environments, and are particularly fond of rodents and birds in these habitats.

Eastern Ratsnakes are currently recognized as distinct from Central Ratsnakes P. spiloides, as well as Western Ratsnakes P. obsoletus. Parts of all three species were once generically labeled "black ratsnakes". Use the "! blackrat" command without the space for more on these changes.

Ratsnakes can be easily distinguished from racers Coluber by the presence of keeled scales. Racers have smooth scales.

Keels are raised lines on the surface of scales that can be used as a character in snake identification to quickly narrow down options or distinguish between some similar looking species. Strength of keel is variable; usually referred to as 'strong' vs 'weak'.
