Ok i have been trying to figure it out, how do you tell the difference between the two? I have many books that try to explain it. Does any one have photos of the two to compare?
Is it pattern, length or number of saddles?

Thanks!
Sarah

Hi Sarah,

Most B.C.C you see are Suriname's or Guyana's but there are a few others too. Most of your B.C.C have some widow peaks / bat wings on there saddles, kind of looks like this and they will have nicer looking tail color mostly red and sometimes orange. Suriname's tend to be more pink / red in body color and Guyana's tend to be red / purple in body color. Now B.C.I will all most never have widow peaks / bat wings on there saddles but there are a few that will have small widow peak / bat wings. There saddles will look like this ) ( most of the time. Also B.C.C will grow slower than the B.C.I but they will get bigger. Here are the scale counts for B.C.C and B.C.I. Boas.

The surface or side of the body normally oriented upwards, the top of the snake, is the dorsal side; the opposite side, the belly is the ventral side. The subcaudals scales are the belly scales from the vent to the tip of the tail. The saddle count is taken from the head to the vent.

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

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

Now here are some pictures of BCC and BCI

These are all BCC boas.

Guyana BCC:

Suriname BCC:

Brazilian BCC:

These are all BCI boas.

This is Zena.

Here are some male BCI

Here are some female BCI.

Here is Giai a female BCI You can see a small widow peak on her 9th saddle.

Take care

Wow thank you so much for the help!! That has been confusing me for some time but this makes it very understandable!
Those are some great photos too!, I think Zena is one of the largest boas i have ever seen. HOLY CRAP!!
I cant wait for my boas to grow up as large as that! well the female anyway lol.

Do the other types of patterns (such as arabesque) come from a different species? Because their saddles are super thin and connected? or are they a simply maybe a BCI with very thin saddles?
