The name is most probably derived from Russian word "зараза" (zaraza), meaning disease.
guess is awesome but I greatly doubt in this. Зараза has a strong archaic flavour and is almost never used in Russian. Nowadays the word is most used as jargonic adjective meaning "nasty","vile"(this was linked to disease long ago) but I don't think this could be a cause of naming. Just IMHO ElfElunaAlina 09:07, 17 June 2007 (UTC)
In Italian and I think in many neolathin laguages razza means ray or more presumably devil-fish since chimaeras fly like a devil-fish swims in the water. Its color are also very similar to a devil-fish. Razza means race too but i think this is not the case. --N'Nanz 15:34, 6 September 2007 (UTC)
