Sandy Dann in conversation with Taryn “The Shell Lady”121225

Radio Goolarri – In Studio 📅 Aired: 12 December 2025 Sandy Dann welcomes back Taryn Ryan – The Shell Lady for another fascinating shell yarn, this time diving into one of the ocean’s rarest curiosities: sinistral (left-handed) shells. Broadcast live from the Radio Goolarri studio on 12 December 2025, this conversation explores how most shells grow in a right-handed (dextral) spiral — and why left-handed shells are so rare they sometimes make museum news. Taryn breaks down the science behind shell growth, genetics and survival in a way that’s easy to understand and full of wonder. In this episode, you’ll hear about: What sinistral (left-handed) shells are and why they’re so rare How gastropods build their shells over time, like bricks on a wall Why shell shape affects mating and survival How rain, tides and fresh water influence shell growth on Broome’s reefs The difference between marine, freshwater and land gastropods Why shells are homes, protection and survival tools — not just beach finds With plenty of curiosity, humour and respect for the natural world, this yarn reminds us just how complex and clever these small creatures are — and why slowing down and observing nature always reveals something new. 🌊 Next time you’re walking the beach or out bush, keep an eye out — you never know what rare story might be right under your feet.
