Redback spider

The redback spider is a dangerous spider endemic to Australia. It is a member of the genus Latrodectus, the widow spiders, which are found throughout the world. The female is easily recognisable by her black body with a prominent red stripe on the upper side of her abdomen. Females have a body length of about a centimetre, while the male is smaller, being only 3 to 4 mm long. The redback spider is one of few arachnids which usually display sexual cannibalism while mating. Redbacks are one of the most dangerous species of spiders in Australia. Its neurotoxic venom is toxic to humans, with bites causing severe pain, often for over 24 hours. An antivenom is commercially available, and since its introduction in 1956, no deaths directly due to redback bites have been formally recorded.
