Redback Spider

The redback spider, also known as Latrodectus hasselti, is one of the most dangerous and extremely venomous species of spider that can be found in Australia, Asia, and New Zealand. They are often called “Australian Black Widow” because they look similar to the Black Widow, but they are totally different in terms of behavior and features. 

In general, the female redback is larger than males and their body can measure ten mm in length (0.1 in). They are nocturnal and feed on different insects, other spiders, and small vertebrates. They catch their prey on their web and attack them by injecting a complex venom. 

Unfortunately, their venom can be deadly to humans as well, but complications can be prevented with an antivenom discovered in 1956.

  1. They left off probably the two most dangerous spiders there are: The Brazilian Wandering Spider (or Banana Spider) and the Funnel Web Spider from Australia. Both can cause death to humans.
