When animals attack #3 Redback Spider



We spotted this little fella hiding out under Joel's ride on car. The body was as big as your thumb nail and Matt says that it was the biggest that he had ever seen in fourteen years! This is an interesting read, particularly the bit about the harsh treatment dished out to the male by the female. Life with Beth not so tough after all!

The Redback Spider is found all over Australia in open bushland, but is especially common in urban areas. As one of a number of spiders that prefer inhabited areas, and because it often builds its web in places like bins, sheds or outhouses, the Redback frequently comes into contact with humans, especially during the summer months. Although not aggressive, over 600 bites occur each year in Australia-often when the spider is accidentally pressed against the hand when cleaning, or lifting material containing a web. Bites are always from females as the male is much smaller and has jaws that are unable to penetrate human skin. The venom is highly toxic to humans but effective antivenom is widely available and no deaths have occurred since its development. As a member of the 'widow' group of spiders, the Redback Spider is also famous for the male's suicidal tendencies. After mating, he spins around so that his abdomen is against the female's fangs, effectively sacrificing himself to her. She mauls him, usually fatally, and eats him. If he escapes, he does so severely injured and returns to mate again-this time to certain death.
