Nautilus pompilius: Species History and Conservation Status

Nautilus pompilius: Species History and Conservation Status

In this podcast, I will discuss the species Nautilus pompilius, its ancient lineage, and its current conservation status. This species traces its lineage to over 500 million years ago, yet overfishing by humans could lead to its extinction in 50 years or less. Listen to this episode if you are interested in learning more about the Cambrian Explosion, the Great Ordovician Biodiversification Event, the five mass extinction events of the Phanerozoic eon, and the life history and conservation of Nautilus pompilius.  Works Cited: Brannen, P.
