Judith Muir inspired us with tales and slides of Port Phillip Bay: Life beneath the sea after U3A's AGM. Judith runs Polperro Dolphin Swims with her family from Sorrento and is a passionate educator. She swims in the Bay daily and observes its waters minutely. She reminded us that 90% of the species found in Victorian waters are endemic - occurring nowhere else in the world. She described 'seagrass is the life force of the bay'. Seagrass needs light to photosynthesise and is made vulnerable when sediment reduces light penetration. Fantastic that you can be exposed to speakers of this calibre through U3A Port Phillip, capably led by a dedicated committee for less than $50 a year. www:u3app.org.au
