BBC - Earth News - Spider builds life-sized decoysThere is a species of spider that builds models of itself, which it uses as decoys to distract predators.
The spider may be the first example of an animal building a life-size replica of its own body.
So believe the scientists who made the discovery, which is published in the journal Animal Behaviour.
The arachnid's behaviour also offers one explanation for why many spiders like to decorate their webs with strange-looking ornaments.
