Nautiluses are the last surviving members of a 500 million year old animal lineage. Their continued existence, however, is under threat from unregulated fisheries and world-wide trade for the nautilus shell. For nearly a decade, the Save the Nautilus team has been assessing the current state of nautilus populations across the Indo-Pacific to support conservation initiatives. Utilizing a combination of methods, including underwater video surveillance and community outreach, the group’s work has led to the first international regulation of the nautilus shell trade, enacted in 2017. In his lecture Gregory Jeff Barord, Ph.D., will discuss monitoring nautilus populations and studying nautiluses and the deep-sea ecosystem as a whole. Barord is a conservation biologist for Save the Nautilus and the marine biology instructor for Des Moines Public Schools’ Central Campus.
