Did the Germans use any other coding system besides the enigma in World War Two?

Yes. Germans utilized teleprinters that had unique ciphering systems for field work. They worked conceptually in a similar fashion to an ENIGMA, typing a message in in plaintext that would then be enciphered via machine (the actual mechanics were quite different). The main difference being that ENIGMA was for morse traffic, the other systems were for text. The teleprint ciphers were all under the FISH umbrella, the two best known being STURGEON and TUNNY. TUNNY was the name given to the first non-morse link and was far less complex than STURGEON, which was actually more complex than ENIGMA. However, most of what was sent via STURGEON would be resent via other channels, so there was less of a need to attack it. TUNNY actually has a very interesting story in the decryption methodology, but because it lacks the capture of a machine, it never really seemed to grip people's attention. Stories of math and reverse engineering are not as endearing as the various captures of ENIGMA equipment.
