Nuance between いか and イカ? [duplicate]

Question

Both mean squid but is there any difference between the use of hiragana or katakana?

Answer 1

イカ is used more frequently. いか is Japanese style, cute and childish. イカ is standard and scientific.

Answer 2

I heard somewhere that animals can be written in katakana to make they seem more cute or playful.

Examples: 鴨: ooh, so foreign, fancy かも: standard カモ: playful, cute, childish, advertising appeal
