Redback spider

The redback spider is a venomous spider that lives in Australia. The female is larger than the male. The female's body is about 1 centimetre long and the male's body is about 3 millimetres long. The adult female spider is usually black and usually has a red stripe on its back. The female likes to live in warm sheltered places and makes a web to catch insects and other small creatures.
The spider's bite can be very painful and dangerous to people, because it can inject a venom through its fangs. An antivenom injection is available, which can help to restore the health of people who have become very ill after being bitten by the spider.
