Alt text:
If you live in Los Angeles (around 33°52'N, roughly the latitude of Hermosa Beach) the black hole in V404 Cygni passes over you each day. On Christmas Day it will be directly overhead around 2pm.
Unless the animals have developed a way to move for miles every day, there should be predators who are adjusted for the night side, and predators who are adjusted for the day side that would be well known and defended against from the prey on their side. For a sentient species, figuring out how to defend against one or the other shouldn't be too hard.
What would be harder to defend against would be those predators who live in the twilight areas are close to both day & night.
Kinda. I imagine the GP meant predators that live on the border of night specializing in devouring anything that makes a wrong errand and ends-up there. Like the ones we have at the bottom of the ocean.
On a second thought, I don't think they would be very scary. Probably mostly scavengers.
Is GP me? Haven't heard of that but I assume it's similar to OP. In case it is, I elaborated a bit in another reply!
Grand parent; the comment you were replying to.
