I was looking through a list of words that normally are written in kana, instead of their kanji. Two caught my attention because the list has them written in katakana, instead of hiragana. But, as neither are 外来語, writing them in katakana seems strange.
When given no context, is it true that both "honey bee" and "dolphin" are written in katakana (instead of hiragana)?
(Note: I do not care about any theory as to "why" they are exceptions. Simply, when there is no context and they are just words in a list, should both be written in katakana?)
Here is the full list of animals written in kana, instead of kanji:
あかんぼう baby, infant
うさぎ a rabbit
きつね a fox
くらげ a jellyfish
とんぼ dragon fly
ミツバチ honey bee
やもめ a widow
りす a squirrel
