My friend sent me these pictures of a pool that has been abandoned for a long time, and we are curious about the reason behind the peculiar growth of algae in this pattern. The needle-like towers of
It’s even more extreme in water, though, because the light closer to the bottom is literally dimmer. In a forest any sunlight that penetrates the foliage will be just as strong as it is in the canopy, but in water it loses strength as it penetrates deeper. That might be what makes the spikes so sharp, whereas surface plants have gentler slopes towards the upper layer of the biosphere.
Indeed, also why most marine life actually happens to be very close to the shore in shallow waters. Most of the ocean is basically a desert as far as life is concerned.
