Redback Spider
The Redback spider has the same features as the Black Widow, but you can further distinguish this creature through its color. The female Redback spider is black with a red stripe at the back and the unique red-orange hourglass on the underside. This spider is mostly found in Australia, but its species already spread to countries like Belgium, New Zealand and Japan. Sweating, vomiting, muscle spasms and pain are some of the symptoms of this spider’s bite.
