Boomslang (Dispholidus typus typus) with partially inflated neck. When provoked or threatened, the boomslang will inflate its neck to twice its size to appear larger and expose the bright skin between the scales. This snake is native to parts of sub-Saharan Africa and is arboreal and terrestrial. Boomslangs are rear-fanged and although their venom is extremely poisonous they are shy, non-aggressive snakes and few bites are recorded. The snake in this image is a male snake with female colouration. Photographed in controlled conditions at the Hoedspruit reptile centre, Limpopo province, South Africa.
