Note
Day-night comparisons of the motile epifauna in the canopy of seagrass beds in the Indian River lagoon, Florida revealed that abundances were not stable over the diel period. Collections were made between February and June, 1982. Higher densities of epifauna occurred on seagrasses at night. For both of the numerically-dominant gastropod and crustacean groups, four of the five top ranked species followed this diel pattern.
