Hello, It's an unusual feature of Engish that it uses a number of foreign plural endings, where the suffix was "imported" together with the foreign word, e.g. larvae, fungi, bacteria, analyses, mafiosi, paparazzi, châteaux, kibbutzim, eisteddfodau etc. Also in German, there are some foreign words that take a foreign plural, e.g. Streiks. (This would be impossible in Hungarian, where all nouns take the plural suffix -k.) Do you know about foreign plurals used in other languages?
