HISTORY & FACTS: The National Marine Fisheries Service gave Endangered Species Act protection today to the chambered nautilus, which is threatened with extinction due to over harvesting for the international shell trade. Over the past 16 years, nearly 1.7 million nautilus shell products were imported into the United States.
Nautilus shells were popular items in the Renaissance and Baroque cabinet of curiosities and were often mounted by goldsmiths on a thin stem to make extravagant nautilus shell cups.
Mathematicians have learned to use Fibonacci’s sequence to describe certain shapes that appear in nature. These shapes are called logarithmic spirals, and Nautilus shells are just one example. You also see logarithmic spiral shapes in spiral galaxies, and in many plants such as sunflowers. Nature forms these spirals in the most efficient way possible, and mathematicians have learned to describe them, using Fibonacci’s sequence.
