I will tell you about how these spitting cobras spit venom. The palato-maxillary arch (comprising the pterygoid, palatine, ectopterygoid and maxilla) articulates with the skull at the prefrontal (black rectangle). Immediately adjacent to the palato-maxillary arch is the venom gland and duct; the fang sheath covers the anterior portion of the maxilla and venom duct. The system at rest is shown from a lateral (A) and dorsal (B) perspective. Upon contraction of the M. protractor pterygoideus (PP) the palato-maxillary arch is protracted, rotated in the sagittal plane (C), and rotated in the frontal plane (D). These rotations displace the fang sheath (D,E), removing barriers to venom flow such that when the M. adductor mandibulae externus superficialis (AMES) contracts, venom pressure can expel venom through the specialized exit orifice of the fang (E). P, pressure; F, fang. The second picture's description is her,Muscle attachment sites are shown as solid colors (lateral surface) or broken colors (medial surface) for the following muscles: M. adductor mandibular externus superficialis (yellow); M. levator pterygoideus (purple); M. protractor pterygoideus (red); M. retractor pterygoideus (blue); M. pterygoideus (green). e, ectopterygoid; m, maxilla; pa, palatine; pf, prefrontal; pt, pterygoid.
These snakes are very dangerous and I've seen them twice in Kenya.They have great accuracy[greater than other spitting cobras] in spitting venom on the eyes.They can spit from 4 to 8 feet (1.2 to 2.4 meters).
The Mozambique Spitting Cobra has a wide Geographical range true the African continent it occurs in Natal , Swaziland , Mozambique , which gave this snake his name, Transvaal , Zimbabwe , east and north Botswana , north-eastern Namibia , south-eastern Tanzania , its also known from Zanzibar but is quite rare there. The Mozambique Spitting Cobra also occurs south of lake Tanganjika in Malawi , and southern Zambia . In East Africa can Mozambique Spitting Cobras been found below 1000 m altitude, but in Southern Africa are they also found up to 1800 m altitude.
Want more? :wink:
