The full length of a fully developed male is almost 1.6 m (5.9 ft),  while that of a female is 2 m (6.6 ft). This snake  occasionally reaches a length of 2.5 m (8.2 ft). Generally the full length is 4 to 4.3 times the tail’s length. The Eastern Green Mamba has a thin, lengthened head, in the shape of a coffin. From the neck, the canthus (or the canthus rostralis, represents the angle in between the side of the head between the eye and the snout  and the flat crown of the head),  and is clearly visible. If this animal is terrorized or aggravated in any way, it can flatten its neck without any formation of a hood. The front fangs of this snake are comparatively long,  situated in the front of the maxillary bone right in front of the maxilla and can rotate around its axis with the help of the pre-frontal bone, whereby they have sufficient control of the movement of their fangs, quite different from the other varieties. There are no hard teeth in the maxillary bone. Even then, on the frontal portion of the lower jaw, there are two long recurved hard teeth in the form of fangs, behind which there is a clear space at intervals. In the front of the jaw, there are a number of tiny teeth. These green snakes have circular eyes with round shaped pupils.

These male green mambas challenge each other by performing a ceremonial dance or by wrestling and competing with each other on the ground, where the stronger one makes the other to surrender. This type of battle lingers for hours. Persuading the female towards sex and mating is done on the trees. The female lays about 10 to 15 eggs. After a period of 3 months or more, the mamba babies hatch;  the hatchlings are almost half  a meter in length.
