She's here!

[Twist]

A while ago I posted that i'd be getting an aggressive female rtb. I finally got her, she's not aggressive at all. Im curious though if you guys have any ideas to her locality/morph. Here ya go!

She's pretty. Glad she's not agressive towards you

Very pretty. I'm really not good with the boa morphs yet, but better pictures would probably help a lot.

here's some higher quality pictures. Sorry for the delay.

She is pretty! I don't know her morph tho, sorry.

She looks like a normal columbian BCI to me - I should say she's definitley a BCI although she could be a specific subspecies/locality. Unfortunately, that would be impossible to say for sure though if you don't have paperwork from the original breeder. BCIs vary greatly in appearance so there's no real way to make a sure guess on locality.

Now her pattern could be referred to as "circle back ladder tail" but to be clear, that is really a description of pattern and not specifically a morph per se. The pattern could be genetic, but it might not be.

No matter what, she's a very pretty girl! I love her speckled belly! And the spotting on her head is quite unique. I am glad she's not aggressive - you have a very nice girl there for sure!

Thank you! I figured finding out if she's a specific morph would be a long shot but who knows, maybe someone on here has one exactly like her and knows. How do you tell the difference between a BCI/BCC etc? Just the locality and such?

Red Tail Boas are classified as follows:

Boa Constrictor Constrictor (BCC)- These are the "true red tails." These are generally the largest in size and maintain their red tails into adulthood. The tail will normally have a distinct red color that ranges from bright red to a deeper, more blood red color. They come from:
Peru
Brazil
Venezuela
Suriname
Guyana

Boa Constrictor Imperator (BCI)- This is the largest group of boa constrictors. Their tail color normally ranges from a darker, more subdued red to a more common brown color. They include the boas from Central America:
Colombia
Panama
Costa Rica
Nicaraqua
Mexico: Tamaulipas, Tarahumara
and the insular islands:
Hogg Island
Caulker Cay
Crawl Cay
Corn Island

Boa Constrictor Amarali (BCA)- Bolivian boa constrictors

Boa Constrictor Longicauda (BCL)- These come from the Tumbes region of Peru. They are also known as the Peruvian Long-tail Boa, as they have a higher scale count from their vent to tail tip, than the Peruvian BCC.

Boa Constrictor Occidentalis (BCO)- Argentine boa constrictors.

Boa Constrictor Sabogae (BCS)- Pearl Island boa constrictors

As well as, some of the lesser known sub-species:

Boa Constrictor Nebulosa- Dominican Republic, Lesser Antilles
Boa Constrictor Orophias- St. Lucia
Boa Constrictor Melanogaster- Ecuador Black Belly

It is best to research each of these, as they have different sizes, colorings, and growth rates. Here are a few websites to help you get started, where the different sub-species of Boa Constrictor are discussed and described:

Physical Differences:

-Saddle Shape: Generally the BCI saddles will have a rounder apearance, looking something like this: ( ) ( ) ( ), whereas the BCC saddles generally have an apex in the saddles, much like this: } { } { } { } . While this is a good marker, it is not always reliable.

-Head Shape: The head shape between BCC and BCI may be hard to detect in neonates, but from about 1 year in age, the differences become more apparent. The BCC generally have less pronounced jaw muscles, giving the head a more slender, longer, or uniformly tapered appearance, with a more pointed shaped nose. Also, the size of the head will appear larger in relation to the size of the body in the neck area. The BCI generally has more pronounced jaw muscles and a more blunt or broader looking nose, giving the head a shorter appearance. Also the BCI head will appear smaller in relation to the size of the body in the neck area.

-Scale Count: Scale count is another indicator of Boa type, however, since alot of the numbers overlap, it should not be relied on solely. Scale count + Head shape is the most accurate method of determining the type of Boa that you have. If you are looking for a specific locale of BCC or BCI, the easiest way to ensure that you are getting what you want is to buy from a reputable breeder who will guarantee the genetics.
Here is a chart that was posted on another forum with some basic scale and saddle counts. I left the authors name in the post so that he can recieve credit:

Here are the scale counts for you.

BCC
scale counts - 75 to 95 dorsal rows.
227 to 250 ventrals.
49 to 62 subcaudals.
Average 15 to 21 saddles.

BCI
scale counts - 56 to 79 dorsal rows.
225 to 253 ventrals.
47 to 65 subcaudals.
Average 22 to 30 saddles.

BCA ( Amaral Boa)
scale counts - 71 to 79 dorsal rows.
226 to 237 ventrals.
43 to 52 subcaudals.
Average 22 saddles.

BCL (Longicauada)
scale counts - 60 to 76 dorsal rows.
243 to 247 ventrals.
50 to 67 subcaudals.
Average 19 to 21 saddles.

BCO (Occidentalis)
scale counts - 65 to 87 dorsal rows.
242 to 251 ventrals.
45 subcaudals.
Average 22 to 30 saddles.

Hey thanks for reposting that info xFenrir! That was an excellent post Vypyrz made a few months ago. I had tried to find it once before and when I had trouble locating it, I bookmarked it once it turned up. All really great info and very accurate. But you beat me to it in reposting it for this time, lol!

She's gorgeous! Congrats on her.
