How does it feel to find the world's longest organism? Which sea slugs look like David Bowie? This week the Particle Podcast takes a deep dive, right down to visit the sea slugs. Our guide is molecular marine biologist Dr Nerida Wilson. She joins the podcast to chat about world travels and unexpected career paths.   Particle Podcast is about science and the people who just love it. It's produced and presented by Rose Kerr (@rosie.zkerr). You can find more Particle at particle.scitech.org.au or @ParticleWA on Twitter and Instagram.
