@KakaniKatija hm idk how much species overlap there is here. but yeah, looks like they see best between 470-500nm, so not very close to the red end of the spectrum at all. https://t.co/9tVXZU8khy

調べてみたら、普通のイカは色盲みたいですが、ホタルイカは色覚がある模様。あとはよろしく…。RT 異世界人類 vs ホタルイカとの戦いの鍵を握る技術となるか、異世界人類の滅亡の危機において、ホタルイカの目玉が決定的な解決策をもたらすか。https://t.co/2lj0uewubN
