Question

i dont have much info about it, except:
-it was seen in florida
-it is black, white, brown, and like a mustard color
it was in my relative's yard, and if you are able to find a snake that fits the description, i would like to see a picture and i would like to know if it is poisonus
i have no idea if it had diamonds or stripes or if the colors were all mixed in
i would really appreciate the help even though i dont have enough info about it
please help me out if you can

Answer 1

Sounds like a Corn Snake...the farmers friend.

The color pattern can vary in subspecies.

The one we have in the education department at the zoo is a mustard color.
