white rhinoceros
Refers specifically to the species Ceratotherium simum. In Japanese, animal names are commonly written in katakana.
I saw a white rhinoceros and its calf at the zoo.
Katakana spelling is standard for this animal name; usually written in kana.
Kanji spelling exists but is rarely used; it is not a priority form.
Compound of 白 (しろ, 'white') + 犀 (さい, 'rhinoceros'). The English name 'white' is a mistranslation of the Afrikaans 'wyd' (wide), referring to its wide mouth.
