I found this today and thought it was good to know, if you live in Texas.

(1) the sales receipt for the transaction is a temporary recreational controlled exotic snake permit valid for 21 days from the date indicated on the receipt;

These are the snakes that Texas regulates.

(2) Controlled exotic snake--Any live snake that is:

(A) a venomous snake not indigenous to Texas;

(B) any of the following:

(i) African rock python (Python sebae);

(ii) Asiatic rock python, (Python molurus);

(iii) green anaconda, (Eunectes murinus);

(iv) reticulated python, (Python reticulatus);

(v) southern African python, (Python natalensis); or

(C) a hybrid of any species listed in this paragraph.

These are the two types of permits Texas has.
