Animal vision: Colossal eyes

Do monsters have monstrous eyes? While the kraken is (almost certainly) a mythical being, that is not to say that there are not monsters living in the depths of our oceans. And even monsters have eyes; rather large ones, as it turns out. When it comes to eyes, giant squid and their even larger relative, the colossal squid, really do live up to their names. Their eyes are far bigger than those of any other animal, even ones larger than themselves living in the same environment. There are many questions surrounding these mysterious animals, one of which is what they are using their excessively large eyes for.
