The son of an enthusiastic sports fisherman, Guido became fascinated at a young age by marine life during yearly holidays in Brittany, France.

This allowed him to dive in many parts of the world, in European waters and in many tropical seas from Baja California to Queensland, Australia.

In 1999 with Klaus Groh, he started the prestigious series "A Conchological Iconography", which today is one of the biggest compilations of its time.

The following volumes have already appeared: Poppe also wrote dozens of popular articles in journals and magazines such as Hawaiian Shell News, Of Sea and Shore, Malacologia, Apex, Novapex, Musorstom, Informations, Gloria Maris, Visaya etc.

As a collector he built major conchological collections, which are now housed in prestigious museums all over the world: Guido Poppe has described 538 species, genera, subgenera, families, subfamilies and tribes.
