Usage notes

When written in kanji, this form is used to indicate the food made from the roe of the sea animal, and the other kanji forms refer to the animal itself, rather like the distinction between the words cow and beef in English. As with many terms that name organisms, this term is often spelled in katakana, especially in biological contexts (where katakana is customary), as ウニ.
