History of the lock

 In November 1937, an unusual creature was discovered in Mariehov Lock, which turned out to be a Chinese mitten crab. These are an Asiatic variety which was spread to Europe by ship. The lockkeeper who discovered it handed it over to a headmaster in Söderköping by the name of Hultén for forwarding to Professor Hanström in Lund. What then happened to the crab remains a mystery.
