1. Redback Spider
The redback spider tops the animal lovers list because this arachnid would literally kill for some action — and does! The courtship begins with the male back-flipping into a sexual position, taunting the female by placing his rear directly in front of her venomous fangs. Guess that’s one way to say, “Come and get it!” The female happily obliges, taking a bite out of her lover, but before the poison sets in, the male scurries away from her deadly embrace. Too bad he can’t leave well enough alone — he eventually returns, only to be eaten by the female. Well … that’s one way to avoid any awkward, serious relationship discussions!
