15.09.2014 20:05 (ranger with flashlight) Spiders prey on the shrimp. The spiders reflect the flashlight white, the shrimp's eyes reflect the flashlight red. Zoom in to see part of a shrimp in the spider's mouth and the red dots (shrimp's eyes) in the water.
16.09.2014 6:00-6:15 I saw only two shrimp.
Conclusion: go at night to see snakes and spiders preying on shrimp, go in the morning (just after sunrise) to see shrimps in daylight.
