i was recently at a local pet shop that my buddy works at and in one of the tanks filled with baby water snakes there was a noticatly differnt snake in the mix of about 2 or three dozen water snakes . this looks like a garter/ribbon mixed with something else
i knwo garters can be born without a stripe or the two side stripes but this ones noticably differnt, in underneath and head is that like a black racer , very differnt scales from any garter ive found in here, my buddy at the pet shop said it was a local someone braught in and didnt know whut it was. its all black ontop and the head as well with only one stripe very bright green/kinda whiteish , that i very sharp and not unlike those that are usualy found in this area , its definately not mixed with a ribbon although it has ribbonsnake like features .its underneather is verydark solidly with darkblueish racer like color to it from tail to head with no design just flat plaint shaded color .

i live in the philladelphia area of pennsylvania .ive been catching snakes n such aroudn here and evrywere else i go my whole life ,the only other wierd garter ive ever caught was blue striped instead of the usual black as well as a white stripe instead of the usualy back. im very familiar with almost every species in northamerica and still cant pinpoint what this would be

any suggestions ?
