No moon shrimp are photodependent so follow the sun.
if they're "photodependant" why would the eclipses be abnormal, if anything they would be constant as the moonshrimp try to get closer to the sun. Also if the sun could be blocked out by a moon in a solar eclipse, then the sun would have to be above the sun, obviously, but if they are essentially disc shaped, how would the shrimp get their light from the sun at all?
Maybe my issue is more with these moonshrimp than anything, any chance i could get a explanation to what they are or how they work?
