Corn Snake Morphs Chart & Morph Explorer

Good to know. Swatches are simple drawings made from each morph's written description, not photos, and real snakes vary a lot within a morph. Inheritance follows Ian's Vivarium's morph guide. We don't list prices.

Corn snake morphs chart (full list)

This corn snake morphs chart lists all 28 morphs in the explorer, with their colours, pattern, eye colour and inheritance. It works as a quick corn snake morph list: click a name to jump to its card and swatch above. Ian's Vivarium's morph guide catalogues 995 corn snake morphs in total, so this is a selection of the most important base genes, localities and combinations rather than every name on the market.

There are three broad types of corn snakes in this chart. Some are localities or line-bred looks, such as Normal (Carolina), Okeetee and Miami, which describe natural colour forms. Others are single-gene morphs, each caused by one mutation that changes colour (amel, anery, caramel), pattern (motley, stripe, tessera) or scales (scaleless). The rest are combinations of two genes, such as snow or butter. New combinations appear every year as breeders mix genes, which is why counts run into the hundreds.

Most popular corn snake morphs

Corn snakes are one of the most widely kept pet snakes, second only to the ball python according to Wikipedia, and part of their appeal is the range of corn snake colors. We found no sales data ranking morphs, so instead we list the ones our sources describe as common or widely bred. These are the most popular corn snake morphs you are likely to see at a shop or reptile show:

• Normal (Carolina) and Okeetee: normals are "the most commonly seen" corn snakes (Wikipedia), and Okeetee is "the most common locality on the market" (reptile.guide). The Okeetee corn snake has deep red saddles with thick black borders on bright orange.
• Amelanistic: the oldest morph, first bred in captivity in 1961 (Ian's Vivarium), and the base of many combinations.
• Hypomelanistic: "one of the most common colour morphs" (reptile.guide).
• Motley: "the most common pattern morph" (reptile.guide).
• Snow: listed first among popular combination morphs on Wikipedia.
• Anerythristic: widely bred and used in ghost, granite and snow combinations (reptile.guide).

Rare corn snake morphs

"Rare" in the hobby usually means new, hard to breed or slow to produce, rather than biologically rare. Our sources describe these as rare corn snake morphs or hard to find:

• Palmetto: traced to a single wild-caught adult male from South Carolina. Breeder Don Soderberg of South Mountain Reptiles acquired it in 2009, and the first visual babies hatched in 2012. A palmetto corn snake is clean white with scattered coloured flecks, and South Mountain Reptiles and reptile.guide both call it one of the most sought-after morphs.
• Scaleless: a scaleless corn snake keeps its belly scales but has few or none on its back. reptile.guide describes it as very sought-after, with scaleless combinations among the most expensive corn snakes.
• Microscale, Sunrise and Terrazzo: reptile.guide describes microscale as rare, sunrise as "still somewhat rare" and terrazzo as "still uncommon". They aren't in the explorer because we couldn't verify enough detail about them.
• Charcoal and single-gene caramel: not rare genes, but reptile.guide notes charcoal is a little harder to find than anery and plain caramel isn't especially common on its own.

Corn snake color morphs explained: amelanistic, anerythristic, hypo, lavender, caramel

Corn snake color morphs work by removing or reducing one of the pigments a wild corn snake makes. Knowing which pigment is missing makes most morphs easy to recognise:

• Amelanistic (amel, "albino"): no black pigment (melanin). An amelanistic corn snake is red, orange, white and yellow, with pink-red eyes. It was the first corn snake morph: the original snake was caught in North Carolina in 1953 and the first captive-bred amels hatched in 1961 (Ian's Vivarium).
• Anerythristic (anery): no red or yellow (erythrin) pigment, so an anerythristic corn snake is black, grey and brown. Many develop a yellow neck as adults from carotenoids in their food, and natural anery populations live in southern Florida (Wikipedia).
• Charcoal (anery B): a different gene that looks similar to anery, with more muted contrast and often no yellow (Wikipedia, reptile.guide).
• Hypomelanistic (hypo): less, but not zero, black pigment, so reds and oranges glow. Unlike an amel, a hypo keeps dark eyes (Wikipedia). Sunkissed is a separate hypo-like gene that also rounds the saddles.
• Lavender: a lavender corn snake hatches dull grey and matures to pale pink-lavender with purple-grey markings and ruby to burgundy eyes (Wikipedia, reptile.guide).
• Caramel: a caramel corn snake swaps red for yellow and brown: a yellow to yellow-brown ground with caramel to chocolate saddles (Wikipedia).

All six are single recessive genes (Ian's Vivarium), so a snake needs two copies to show the colour. The explorer's Base colour filter groups them by how they look; the Eye colour filter finds the red-eyed amel-based morphs and the ruby-eyed lavender ones.

Pattern morphs: motley, stripe, tessera, aztec, diffused

Pattern genes change the shape of the markings rather than their colour, so they can be combined with any colour morph:

• Motley: a motley corn snake has a plain belly with no checkers and an "inverted" pattern of spots, dashes or a ladder along the back (Wikipedia, reptile.guide).
• Stripe: three or four lengthwise stripes and a plain belly; the stripes may break into "cubes" (Wikipedia, reptile.guide).
• Tessera: a tessera corn snake has a thin, dark-edged stripe down the back that squares off the blotches and pushes them down the sides. It was the first known dominant corn snake mutation (reptile.guide).
• Aztec: a wild, broken zig-zag pattern in scattered patches (reptile.guide). Unlike the others, it is a selectively bred look that doesn't depend on a single gene (Wikipedia, Ian's Vivarium).
• Diffused: blurs the side pattern and removes the belly checkers, and the pattern fades with age (Wikipedia, reptile.guide). Selectively bred diffused snakes are sold as bloodred: nearly solid orange-red to ash-red adults.

Scaleless is listed with the patterns in the explorer because it changes texture rather than colour.

Combo morphs: snow, blizzard, ghost, butter and more

Corn snake morph combos are snakes with two or more mutations at once. This is how corn snake morphs are made: a breeder pairs snakes carrying different genes, raises the offspring, and pairs those again until some babies carry two copies of both genes. The combination gets its own name:

• A snow corn snake (amel + anery) hatches white with pink blotches and becomes mostly white with ivory, pink or yellow tones (Wikipedia).
• A blizzard corn snake (amel + charcoal) is almost totally white with red eyes and little or no pattern.
• A ghost corn snake (anery + hypo) shows soft greys and browns, often with pastel lavender, pink or tan.
• A butter corn snake (amel + caramel) is a two-tone yellow snake.

Ian's Vivarium lists hundreds more, with three, four, five and even six genes combined. Try any pair of recessive genes in the genetics helper above to see its name.

Corn snake genetics made simple

Every corn snake carries two copies of each gene, one from each parent. Corn snake genetics comes down to how a mutated copy behaves next to a normal one (Ian's Vivarium classifies every morph this way):

• Recessive: the snake only shows the trait with two copies. With one copy it looks normal but is "het" (heterozygous) and can pass the gene on. Most recessive corn snake morphs are base genes: amel, anery, charcoal, caramel, hypo, lavender, sunkissed, diffused, motley, stripe and scaleless.
• Dominant: one copy is enough to show the trait. Tessera is the best-known dominant corn snake gene.
• Co-dominant (incomplete dominant): one copy gives an in-between look, two copies a stronger "super" look. Palmetto works this way: one copy looks hypo-like, two copies give the white palmetto look (reptile.guide, Ian's Vivarium).
• Combinations: two or more genes together, such as snow (amel + anery). For a recessive combo, the snake needs two copies of every gene involved.
• Localities and line-bred looks: Okeetee, Miami, bloodred and aztec are shaped by selective breeding rather than one simple gene.

Some genes are alternative versions of each other at the same spot on a chromosome ("allelic"). Motley and stripe are an example, and motley is dominant over stripe: Wikipedia explains that breeding a stripe to a motley gives all motleys, and breeding those offspring together gives about three motleys to every one stripe. Amel is similarly allelic to a gene called ultra (Ian's Vivarium). That is why the genetics helper won't combine motley with stripe.

Do morphs affect a corn snake's size, lifespan or health?

For most morphs, the evidence says no. We found no vet or scientific source showing that any colour or pattern morph lives longer or shorter than a normal corn snake, so the same 10–20 year range applies; see our corn snake lifespan calculator for the details. Size is mostly about bloodline and feeding rather than colour, though Wikipedia describes Miami-phase snakes as usually smaller and reptile.guide says cinders are often slimmer. Our corn snake size calculator covers normal growth.

A few morph-specific notes are on record. Early bloodred lines tended to lay large clutches of small eggs that hatched into hard-to-feed babies, although Wikipedia notes this is no longer the case. reptile.guide reports that breeders largely stopped working with a gene called calico partly because unattractive blistering developed under its white patches. Scaleless snakes still have their belly scales (Wikipedia). If you notice skin, eye or feeding problems in any morph, see a reptile vet.

How to use this corn snake morph explorer

Pick a base colour, pattern, eye colour or inheritance type, in any combination. The grid updates straight away and the counter shows how many of the 28 morphs match. Each card shows an original swatch drawn from the morph's colour description, a short description, how it is inherited, which genes make it if it is a combination, and a rarity or health note where a source gives one. If nothing matches, the explorer says so; set a filter back to "Any" or press Reset filters.

The genetics helper takes any two recessive genes and shows the name of the double-trait morph they make, using the combinations listed by Ian's Vivarium. It doesn't calculate breeding odds, because real results depend on what each parent carries. For a full genetic calculator, Ian's Vivarium offers one on its site.

How to work out which morph your corn snake is

Morph names are often guessed from photos, and many snakes carry several genes, so treat any identification as a best guess unless the breeder can tell you the parents' genetics. These clues, taken from the descriptions above, narrow it down quickly:

1. Look at the eyes. Red or pink eyes point to an amelanistic-based snake (amel, snow, blizzard, butter, opal, fire). Ruby to burgundy eyes suggest lavender. A hypo, by contrast, keeps dark eyes even though its colours are bright.
2. Check for black. No black at all suggests amel; reduced, brownish black suggests hypo or sunkissed; black, grey and brown with no red suggests anery or charcoal.
3. Turn it over. A black-and-white checkered belly is the normal pattern. A plain belly points to motley, stripe or diffused (and bloodred).
4. Look along the back. Saddles are normal; spots, dashes or a ladder mean motley; long lines mean stripe; a thin dark-edged line with squared blotches pushed down the sides means tessera.
5. Remember that colours change with age. Lavenders hatch dull grey, snows hatch white with pink blotches and mature to ivory or yellow tones, and diffused patterns fade as the snake grows (Wikipedia, reptile.guide), so a hatchling and an adult of the same morph can look very different.
6. Ask about hets. A normal-looking snake can carry hidden recessive genes. Only breeding records, or test breeding, can tell you what it carries.
