A tense video has emerged from South Africa of a snake catcher releasing a 2.4-metre black mamba - Africa's most feared snake.<br /><br />In the clip, which was filmed on Saturday (September 2) in Limpopo Province, the snake catcher tips up a plastic container, opens the lid and then retreats quickly.<br /><br />The snake doesn't immediately come out, so the man uses an implement to tip up the container and the long snake emerges.<br /><br />For a moment the mamba appears defensive, like it may be getting ready to strike but fortunately is crawls away into the South African bush.<br /><br />The snake was caught near a home and had to be relocated, according to the filmer.<br /><br />Although black mambas are rightly feared for their extremely toxic venom, attacks on humans are rare and they usually try to avoid confrontation.
