Viewed under a magnifying glass, the Vietnamese centipede could easily pass for a monster from outer space, an evil monster for that matter. Though the species is collected and kept as pets by people who collect such things, it is large (for a centipede), extremely fast, aggressive, and has a venomous sting.Most centipedes are predators and most have a toxic sting. Among the 1,500 or so species known to exist, only a few pose a real danger to humans, but one of those that can is the Vietnamese centipede. Most centipedes have a milder venom and most, being smaller cannot penetrate human skin with their fangs. The fangs by the way are not the type of fangs usually associated with teeth, but are rather a part of the centipede’s front pair of legs.
