From this material published Knudsen in 1944, his first work on the new way Jousseaumiella concharum from the family Galeommatidae that in Commensalism with a bridge animal (Gephyrea) and a polychaete (Polychaeta) in empty casings of mitridae lives.

Knudsen obtained a Master of Arts degree in January 1945 and in the summer of 1945 after the Second World War he was invited by Viggo Jarl, a wealthy businessman, on his yacht, the “Atlantide”, on a scientific expedition.
