The second new moon after the winter solstice has ushered in the Year of the Snake, which we're marking with snake extremes -- from largest to most venomous.
While Chinese New Year is just underway, 2013 began with the discovery of a new venomous snake in January. The snake, Thelotornis usambaricus, was found in the northern Mozambique province of Nampula. It's a type of back-fanged snake that belongs to the family Colubridae, illustrated here with the species Coluber caspius.
These snakes can be deadly. Their venom destroys red blood cells, disrupts clotting and can lead to tissue damage.
