My boss at work was golfing in Mexico at Punta Mita 45 minutes north of Peurta Vallarta last week and saw a snake. Knowing me to be a herp enthusiast he asked me to identify it from his description. Needless to say I was clueless:
It was bright green or yellow green with no discernable pattern
It was about 3 feet long
Its head was broad, reminiscent of a Viperidae
Someone there called it a "vebolla" and said it was highly venomous (I'm not very confident in the accuracy of this last statement).
If anyone has a clue as to what it could be, please let me know
