Definition
The emerald tree boa has a large, bulky head that is clearly distinguished from the much thinner neck. The back of the head is defined by two fairly large bulges on either side that contribute to the bulkiness of the head. These bulges may be used as an energy reserve as emaciated individuals often lose these bulges. The bulges slope forward to a snout that is angled such that the lower jaw appears to be shorter than the upper jaw.
