I have a question which feels almost silly -- how do sea animals deal with the changing amount of daylight as seasons change?
In most places this is not an enormous swing, but I am going to Iceland at the peak of summer, and I realized that I don't know if it's worth asking about night dives, since there will be almost no darkness. (I am planning on the "midnight sun" Silfra tour, but there aren't any animals there, so I didn't think of it until I was looking at ocean dives.)
I would guess that the usual night animals simply have less time out swimming when the days get longer, since there tends to be a reason they only come out in the dark. But in the far north & south, this gets quite extreme, so I started to doubt this idea.
Anybody know what really happens?
