Houston Museum Showcases World's Largest Gastropod Shells

Houston, TX – The Houston Museum of Natural Science is currently featuring an extraordinary exhibit within its George W. Strake Hall of Malacology, drawing significant attention to the fascinating world of mollusks. Among the collection are two specimens of Syrinx aruanus, commonly known as the Australian trumpet, which are recognized as the largest gastropod shells on public display worldwide. One of these remarkable shells is an albino, holding the distinction of being the largest albino gastropod shell ever exhibited. These impressive mollusks emerge from unique egg capsules, which females attach to underwater structures like sponges or seagrasses to prevent them from washing ashore. Upon hatching, the young are approximately a quarter-inch (six millimeters) in length. While most mollusks have a lifespan of only a few years, some species can live significantly longer. Certain bivalves, for instance, are estimated to reach ages between 600 to 800 years, highlighting the incredible longevity found within the mollusk kingdom. The exhibit offers a unique opportunity for visitors to explore the diversity and biological wonders of marine life.
