September 1, 2016 — The world’s most mathematically perfect marine species moved a little bit closer to protection last week when the National Oceanic and Atmospheric Administration agreed to consider listing the chambered nautilus (Nautilus pompilius) under the Endangered Species Act.
The move comes after several years of hard work on the part of conservationists and federal agencies to understand the massive scope of the nautilus trade and how it impacts wild populations. According to that research, nearly 1.7 million of these mollusk shells—the natural embodiment of the Fibonacci spiral—have been imported into the U.S. alone over the past 16 years, where they’re sold for anywhere between $15 and $200. The trade in nautilus shells is so bad that it has all-but depleted many populations of these ancient animals.
Further imports as well as interstate trade would become illegal if the species does gain Endangered Species Act protection.
