In this episode, we delve into the intricate world of animal memory and decision-making with our esteemed guest, Dr. Clint Sergi. He sheds light on his fascinating research involving the memory capacity of the West black widow spider. Through an innovative experiment, Dr. Sergi and his team triggered search behaviors in these spiders by removing their prey from different areas of their webs, effectively 'stealing' it. This allowed them to infer what information the spiders retained about their prey - such as relative size and location of capture within the web. Join us as we explore this interesting study and the broader implications it has for our understanding of animal ecology, evolution, and memory formation.
