[The Lone Ranger]

In most sea turtle species, since the eggs in a given nest are all laid at once, they tend to hatch at pretty-much the same time. But the youngsters do coordinate their emergence. It usually takes them 3 - 7 days to dig to the surface, and then they'll wait until nightfall and all emerge at once. (Presumably, this decreases their chances of being seen and captured by predators.)
