Reproduce without sex

Some snakes steal their venom from toxic toads. This specie of snake is known as Rhabdophis tigrinus; they become poisonous when they eat species of toxic toads. The snakes store the toxins obtained from the toads in glands in their neck. When facing danger, the snakes release the toxins from their neck glands. Pregnant Rhabdophis tigrinus can even pass the toxins on to their young. The toxins protect the young snakes from predators and last until the snakes are able to hunt on their own.
Venoms may be used for stroke prevention
