Koen Fraussen (born 1965)[1] is a Belgian amateur malacologist, shell collector, and expert in the Buccinoidea.
Fraussen was born in Brussels. His interest in the ocean started during family holidays on the Adriatic Sea.[2] He began collecting shells at the age of 2.
Fraussen is a part-time bus driver who also studies whelk shells for the Muséum National d'Histoire Naturelle. In exchange for his curatorial work, Fraussen is given a paratype of each specimen he identifies.[3] Philippe Bouchet considers Fraussen "the world expert" on the Buccinidae.[4]
In 2010, Fraussen and biologist Stefaan Wera released the book Schelpen aan de Belgische kust.[5] With the Muséum National, Fraussen published 20 new species of the Photinae (subfamily of the Nassariidae) as of 2017.[6]
Fraussen is honored by several eponyms, includingBuccinum frausseni, Conus frausseni, Eccliseogyra frausseni, Engina frausseni, Fusinus frausseni, Inquisitor frausseni, Metaal frausseni, Pristiterebra frausseni, and Tomlinia frausseni.[7]
