Figure 3: Postprandial sleep in larval Astyanax is not dependent on the amount of food consumed, regardless of the time of day that feeding occurs.

Correlation of amount of Artemia nauplii consumed with sleep duration in the four hours following feeding with a simple linear regression for surface (A-C), Pachón (D-F), and Tinaja (G-I). A, D, G) Larvae were fed prior to ZT2. B, E, H) Larvae were fed prior to ZT6. C, F, I) Larvae were fed prior to ZT10.
