It is a Lepisosteus and not Atractosteus... what species can not be determined with those pics...Those are much to blurry and at wrong angles to get any good ID..
Excuse me...No it is not obvious and it could be any Lepisosteus by those pics....If you wanted to guess you could but to get a good accurate ID I do not think so...
richard is right, in order to get a solid ID a better pic will be needed; given the shot we have here, i would lean more towards Florida than anything else. again, a better shot would help ID--
