Two sac like poison glands are situated one on either inner side of upper jaw below the eyes. These are probably the modified superior labial or parotid glands. Each gland is. Thickly encapsulated with fibrous connective tissue and mostly covered by a fan-shaped constrictor muscle. Its stretching during biting squeezes poison from gland intcrits duct. Certain specialized teeth attached to maxillary bones are known as fangs. They serve as hypodermic needles for injecting poison into the body by victim.
