Ivy leaves

Ah - I've noticed those leaves but didn't associate the shape with light levels. Are there other plants that behave like that?

I suspect there are many species with variant leaves and that light levels are only one reason. Certainly holly has fewer spiny leaves higher up the plants (i.e. away from browsers) and I imagine this also makes them more efficient photosynthesisers. It's not something I have much evidence for beyond the anecdotal though.
