What is the best time?

[paul monfils]

If you are collecting beach shells of course it really doesn't matter. The same shells will be lying there day or night. But if you are collecting live specimens, many species are active at night that are hidden during the daytime. Such species can often be found during the day by turning over rocks, sifting sand, etc., but at night many such species are actively crawling around and easier to see. Other species are plainly visible both day and night.
