Have you ever seen a canopy like this?

What’s going on with those gaps between the leaves/branches? Turns out there’s this thing called “crown shyness,” a phenomenon observed in some species of trees. The phenomenon occurs when different trees’ crowns do not touch each other, leaving these funky channels of gaps between the crowns.

No one really knows what causes this crown shyness. One theory is that the behavior is adaptive, helping to prevent the spread of bugs/larvae that eat leaves. Another theory is that the behavior develops due to the fact that too-close branches can be damaged in storms and high winds from bonking into one another. Still another theory has to do with light. The behavior develops to help ensure that the leaves of a tree are not blocked by the shade of another tree’s leaves, thus getting an optimal chance for light.

Cool huh?
