Spiders are animals of great cultural heft - divisive and evocative. In this episode, we will focus on what a spider is, and how a spider lives. Tom is joined by Professor Mariella Herberstien, behavioural ecologist, arachnologist and Eurovision Song Contest devotee to discuss the incredible lives of spiders. We discuss social behaviour in spiders, the sensory world of spiders, deceptive behaviour and the functions of webs.
