About it
Many seashells grow in a spiral. As the animal inside grows, it adds new shell at the opening, each turn wider than the one before but the same shape, so the shell gets bigger without changing its form. Mathematicians call this a logarithmic spiral.
People say you can hear the sea in a shell. Tap it and three soft swells of sea-blue light run down the spiral to the opening, and with each one a ripple rolls out of the mouth, widening and fading like a wave. The sound in a real shell is the noise around you, echoing inside it.
