Trugnattern

to the Unterfamilie of the Trugnattern (Boiginae) one counts Nattern (Colubridae), which within the rear range of its Kiefers poison teeth has, with whose assistance bite wounds are produced, so that poisonous secretions from the saliva of the queue can arrive into the body of the booty. With this kind of the Bezahnung one speaks of opistoglyphen poison teeth. However these poisons, are mostly rather weak and only three over one hundred the Trugnatternarten, boom long the Lianennatter and the Vogelnatter, have a sufficient secretion, in order to be able to poison humans lethal. Mainly here strong internal bleedings arise. For bird and Lianennatter no anti-serums exist.

Due to the teeth standing far in front because of the short head and the effective poison the wide-spread boom-long ranks however among the feared queues of Africa. Further well-known Trugnattern is the Erdspitznatter and the Mangroven Nachtbaumnatter. Although also the Ringelnatter (Natrix natrix) had a very weak poison is not it due to the missing poison teeth Trugnatter.
